A lot of America centric answers, so I’ll give a more global one: Ikea or any comparable store which uses cheap meal deals as a loss leader to get you to shop in their store. AFAIK the costco hot dog is the most famous US example.
This being said: eat/cook at home. Rice based meals can be made for as little as a dollar per serving, if you buy in bulk. (Get a cheap rice cooker, it can do more than cook rice, save on energy costs, and takes out most of the hassle.) Potato based meals are also very cheap. Baked potato with a bit of butter contains much of the nutrients you need to survive in the short to medium term.
