Fellow working mom here, fasting definitely works for me! Some nights it’s just easier to buy the kid a pizza and fast.
Aside from that, when I don’t feel like cooking I’ll have some combination of: pepperoni, salami, cheese, macadamia nuts, cheese crisps, pork rinds, beef sticks, etc. Not the healthiest selection, but it’s nice to have a night that feels like a junk food night without actually breaking keto.
I do almost all of my cooking on Saturday or Sunday. Pressure cooker, Sous Vide, grill, oven. Make three things, mass quantities, eat all week. Three is kind of key. It keeps things from getting boring.
I do the same as LeCheffre. I cook on the weekend for the whole week. Before going low carb, I lived on Lean Cuisine, so I need to have something I can microwave in a minute or two when I want to eat.
I am fine eating the same food every day for a week, but you could do your cooking and make different meals for the week. It just requires advance planning.
It’s so rare for me. Though when I was new to the Freestyle Libre, I went to Japanese and ordered lchf food. Glucose went sky high. There must have been a sauce with sugar in it!
Most times I order Italian out, I order the same sort of thing — veal or chicken in a lemon-butter sauce, and I’ve never had them thicken it with flour or starch before, especially after I say “no flour please!” My point is that, if you don’t cook it, you can’t trust it.
Frequently for breakfast/lunch I’ll have an omelette downstairs at the bagel place (I work in midtown NYC). Even though it’s 100% keto, I’m well aware that the eggs are cage-raised junk that I find both nutritionally and ethically problematic. At home I only have pasture-raised eggs. And it’s (obviously) cheaper than having the cage-eggs omelette since I’m cooking it myself! But alas I can’t pop home for lunch, it’s just a tad far from the office.
This isn’t a food or recipe, but for what it’s worth… A lot of times when I’m hungry I forget all the great plans and preparation I made beforehand. So I made a list and put it in my phone, of easy things/meals to eat when I’m hungry. It helps (me, at least)! It isn’t magic, but it’s a good reminder (plus it doubles as a standing grocery list).

I totally get the don’t want to cook thing. I keep cheese sticks, pepperoni, and boiled eggs in the fridge. Bacon and sausage links do require cooking, but it’s only a couple of minutes in the pan for the links, or 20ish min in the oven for bacon (then I slather bacon with cream cheese or ranch dressing.) Bell pepper strips slathered in cream cheese are also good.
Once a week I will cook a big batch of either cabbage soup or taco soup, and enjoy the leftovers for a day or 2. Frittatas are another thing that can be made in big batches, frozen, then popped in the microwave. Versatile and filling. A keto 90 second mug “bread” (mostly egg) is also a quick idea. You can add various (cooked) meat bits and cheese to these.
maybe they breaded the veal and didn’t consider bread crumbs being flour 
I’m sure they coated it with something as it is standard step w that dish
yep, to sugar in so many Japanese sauces. for a Japanese dip with grilled things, i just make my own: mayo with a dash of sriracha
When I don’t feel like cooking I grab a rotisserie chicken from my local grocery store deli and they also have a decent salad bar. Ocassionally they have these giant hot wings that I am particularly fond of.
You can try cooking large batches of things on your days off from work. I picked up some roasts that were buy one get one free last week and cooked both of them. I ate one roast over two days and threw the other in the freezer. Just warm it up and maybe a cup of veg or a quick salad to make it a meal.
Salad. Scrambled eggs with precooked bacon.
Lettuce sandwich
Low carb tortilla sandwich
Bullet proof coffee.
Don’t eat
You cooked before, right? If you used to cook meat, eggs, and so on, it should be easier now because you can eat the same foods minus the potatoes, sauces, and bread.
I used to love cooking, but as I got older I had to let certain activities fall by the wayside. I got rid of most of my cooking gear and now have a little bachelor-pad setup with a microwave, slow cooker, freezer, and small fridge. (No stovetop, no oven.) One advantage of microwave and slow cooker is I don’t have grease everywhere, so cleanup is easy.
On keto I eat 2 meals a day. I have digestive issues and other limitations, so I eat a lot of ground beef, canned fish, cheese, and eggs. Once in a while I make pulled pork. If I ever get to a supermarket I’ll pick up a rotisserie chicken.
I offer the following. Take what you need and leave the rest:
Ignore most of the keto recipes. They’re for people who want to cook. It’s so easy to throw a pork chop or beef patty in the frying pan, turn it over, done. Or cook a roast or several chicken thighs in the oven with minimal seasonings. Why complicate things?
Forget about chopping onions, garlic, peppers, etc. Buy frozen, dried, or canned/jarred alternatives. Or omit them.
Find “dump” recipes for the slow cooker. Dump everything in and cook it all together. No sauteeing onions in a pan, no waiting to add items.
Cook several meals together, but don’t overdo it. You don’t want to be up all night bagging and labeling freezer meals. Maybe cook a triple batch: one portion for today, one to put in a container to be reheated 2 days from now, and one to be bagged for the freezer. This goes for chili, slow cooker recipes, roasts, chicken pieces, etc.
Some things are good hot and then good again cold, so cook lots. Examples include chicken and roast beef.
Any of the following is approximately 20 grams of protein and requires no prep and no cooking: 2.5 ounces of cheese; half a can of salmon; a can of sardines. You can eat any of these plain, or on top of a salad.
Instead of fancy sauces, choose a few favorite condiments, such as Huy Fong Foods chili-garlic sauce (no sugar, 0 carbs). Mustard, mayonnaise, etc.
Premake some seasoning mixes, or buy them if you can find good ones without sugar, cornstarch, and chemicals. Chili seasoning, ranch dressing mix, etc. I have a mix that I originally developed for Italian dressing; I don’t eat salads any more, but I still use it for Italian tomato sauce and other cooking. No chopping of onions or celery, no sauteing–just add a spoonful of the mix to a can of tomato sauce. I get compliments on it all the time:
4 Tbsp garlic powder
4 Tbsp Italian seasoning, oregano, or whatever you got
1 Tbsp basil
1 Tbsp cayenne pepper (or use paprika if you don’t like spicy)
4 tiny spoons white powdered stevia
Use 1 teaspoon of this mix per cup of oil & vinegar, or tomato sauce, or whatever you’re making. Most people would also add salt.
Maybe you can cut way back on vegetables. I’m not a complete carnivore, but I decided vegetables weren’t necessary for my health, and definitely not worth the work and expense.
You also are not obligated to make keto cheesecake, keto pizza, or other desserts/snacks/treats. You can make these once in a while when you really feel the urge.
I do 20-hour fasts; that is, my daily eating window is 4 hours. I don’t feel deprived at all. I tried fasting for 44 hours (e.g., no food from 10 pm Monday to 6 pm Wednesday). I felt fine, except I felt a bit weak during my Wednesday workout. So I quit the longer fasts. However, some people feel good enough to exercise while doing extended fasts.
These are my favourite no cook foods:
Hope you find some suggestions that help 
☆ pre-cooked bacon
☆ canned green beans
☆ avocado
☆ cheese
☆ hard boiled eggs
☆ nuts
☆ canned sardines
☆ berries
☆ Brie
I cook for the week on Sundays usually, at least for my breakfast and lunch to bring to work. I always cook up some bacon and hard boiled eggs to keep in the fridge just to have on hand. If i’m not feeling like cooking I just throw some bacon and eggs from the fridge over some baby spinach with some cheese and make a salad. Al ot of times I cook big batches of soup and keep them in the freezer, it’s easy and gives me the option to be lazy when I want to 
I do love just going to buy the rotisserie chicken at the store, so easy and delicious.
I hate cooking. I have no time for fancy-schmancy keto recipes.
My usual evening meal involves chucking a small steak or chicken thigh on a pan, and in the few minutes that takes to cook I gather a handful of vegie/salad kind of stuff and roughly chop/dress it, maybe add some avocado for creaminess. The meat gets a piece of melting butter on top. Done.
Quicker still - scrambled eggs, a bit of ham/salami/bacon or whatever on the side, a few forkfuls of raw sauerkraut, a bit of tomato. Done.
A bought rotisserie chicken will last a few days and provide several super-quick meals. Just add a quick lemon-cream sauce one day, a vinaigrette dressing the next (or the old mashed avocado treatment), and you can make the same protein taste a bit different over several meals.
