For anyone who is even cheaper and cares more about bodybuilding than taste (although I think it tastes good), I go to a grocery store and get a roast chicken or two, a large cheddar cheese to shred, high fat sour cream, some salsa, and corn tortillas (which are very cheap). You could also get a tomato, lettuce, and guacamole if you want (these things spoil faster). You can make multiple meals out of this in your hotel room, Airbnb or even your vehicle without needing a fork or a plate. I've taken these foods from grocery stores and then went to a park picnic table and fed all my friends.
