This is one of the simplest keto meal I've seen, cheapest too. The average plate cost is $-$2 per plate.
What you will need is a rotisserie Chook ... OK OK @carl Chicken, some celery, some mayonnaise. That's for the salad, and we serve it in some baby cos leaves ... but those are optional.
One small chook will make 4 meals easily, these medium ones from CostCo can make 6.
Pull off the drumsticks and wings, and reserve them as appetizers
Pull the flesh off the carcass making sure not to get all the bones and put those in an instant pot.
Using a cleaver chop the meat into a rough 1/4" dice.
Cut the leaves and white root end off the celery and put that in the instant pot with the bones and grisly bits. Slice the celery length ways then across to make a small dice (1/8")
Add diced Celery to the diced Chicken
Add mayo one spoon at a time stirring in between until the mixture has the right consistency.
Serve in a lettuce leaf.
Meanwhile add any old vegetables to your instant pot, half an onion that's been in the fridge for a week, some herbs (parsley, sage, rosemary, and thyme) some random chillipeppers from the bottom of the fridge. Add a couple of cups of water and pressure cook for 60 mins. Open and taste it, season as needed and put it on for another 60 mins and strain it through a sieve into a bowl for fresh chicken stock.
To make cream of chicken soup, reduce it further by 50% in a pot on the stove, take it off the heat and stir in little cream.
BTW: While writing up this recipe I also found this one for BBQ chicken salad that looks pretty good too https://www.ketogenicforums.com/t/bbq-chicken-salad/1235
