There is a mexican food truck that will give me two meals worth of food for $10. I haven't eaten "fast" food in a long time, but I live in the city. There is an indian grocery store that sells samosas, as well as other items, hot and ready.

I would rather hit a Quick Trip or Circle K before I would touch McDonald's or any YUM! brand, basically any fast food or chain. And I am still not keen on gas station food. I eat from locally owned if I eat out, usually. (grabbing food while going on site at work will cause me to make exceptions: still won't do McDonald's. I have done Arby's if they have a good deal, or Subway has a good meal of the day).

I do go to fast-food once in a while, but in my experience McDonald's is really the worst of them, mediocre is too generous. Not any cheaper for basically cardboard.

Chipotle is stellar if something prepared and warm is needed and you have a fridge+microwave where you’re staying. Ask for extra beans and rice, get a bunch of salsa (and a cup on the side) and a pack of cheap tortillas from another store. You can get four or more meals at 300-400cal each from one bowl, more if you have some cheap chips and salsa with it!

If you have a stove and lettuce, you can really “fancy” it up—plop two spoonfuls of bowl stuff on a tortilla, wrap it up tight, and shallow fry each side until brown. Mmmmmm
