If you don't have a fridge, what kind of stuff do you eat?

The only things I can think of are cereals, granola bars, and some juices that are individually canned. Bread, boxed food such as macaroni and cheese, boxed rice products, beans products, apple juice in individual cans. You could buy fruit and vegetables if you have a juicer for OJ in the morning, but I doubt that you have a juicer right now either. Banana's and several fruits that aren't in the refrigerated sections should be good. It's basically looking through the grocery store and avoiding the refrigerated and freezer sections.
