Bacon and eggs is a very easy lunch. So is heating up leftovers from the previous night. I generally do meat, broccoli or cauliflower with cheese sauce, and a salad for supper. Sometimes rice or potato for the non-ketoers, depending on how I feel. I make Fathead pizza fairly often.
I tend to favor dishes that don’t require much preparation. A pork picnic is ideal, because it’s self-basting, and all you have to do is carve it when it comes out of the oven. If I feel up to making gravy, I get the roux ready during slack time, and while the roast is resting on the cutting board, I make the gravy in the roasting pan.
I have an easy routine for cutting up broccoli or cauliflower, and you can do that as soon as the roast goes into the oven (or stew into the pressure cooker). I usually do the veg in the steamer section of this double-boiler I have (don’t think I’ve ever actually used it as a double boiler, come to think of it!), and I start the water heating while chopping up the vegetable. “Salad” is usually chopped lettuce with halved cherry tomatoes in it. As long as the oven is on anyway, you can slip potatoes in for roasting; otherwise, it takes less time in the microwave, if you’re cooking only one or two. Dessert, if any, can be berries in (sugarless) whipped cream, or heavy cream in a cup of coffee. I sometimes pour some cream over Greek yoghurt—very tasty!
