The local butcher's around my rural paradise are my best friends. We have a few of the standard fast food mongers in "town" but I prefer to put my money into the local fare.. supporting as much as I can, and it becomes a proud chore in food prepping weekly.
I'll get bulk, unfrozen chicken and prep my own nuggets, chunks, whatever and either make a batch of something for the week or prep and freeze to be ready another week. Same with beef, pork, if on a hunt I'll stock venison, hare or boar the very same way.
Yet I admit I'll hit up some fast food now and then; usually either a giant meal at times or I'll get, just as an example, a bunch of tacos or burritos at say Taco Bell and slip in between meals over the course of 2-4 days or something. Arby's, Wendys. Some pizza places too, especially the local joints. I need variety anyway but as long as I don't go crazy on fast food, it seems to have its place. In my endeavors and with my personal goals, at least.
