Costco

I harvest all the meat, chop it up, mix it with taco sauce, shredded cheese, and pinto beans, then wrap it up in several dozen burrito-sized tortillas, then wrap in parchment paper and freeze them. It makes a cheap and delicious ready-to-microwave lunch whenever I don't feel like making something more complicated for lunch.

Then I throw the remaining bones and skin and bits into my instant pot, add a few quarts of water, some salt, some bits of carrot, onion, celery, and make a bunch of chicken stock...which I freeze into ice cubes and use for cooking other things.

I try to get a rotisserie chicken every time I'm there...it's one of the most economical sources of protein you can get.
