It depends on how healthy you want your food choices to be. In terms of cheap, crappy calories, Pop-Tarts are pretty good. Cheap, easy to eat anywhere, and 200 calories each. Up here you can get a box of8 (1600 calories) for $2.50 sometimes, and $2.99 almost anywhere, which is hard to beat. But it is all sugar bad oils, so be a bit careful.
The really cheap ways are cooking your own. Pan fried potatoes, or rice with butter or oil, will both only run you a few bucks for all you can handle. Just not very exciting.
