Chef Boyardee, some of them are really good, sometimes, if you want to flavor it up even more, add a little bit of black pepper. Just make sure you get them when they are a dollar each, CRAZY DEAL
If you bum with a few friends, a can of tomato sauce, a pound of whatever pastas, a big can of chilli beans and sometimes, if you have the money, a fresh vegetable of your choice that you add to the mix. This whole meal is really good tasting and about 1,50$ each. I've been eating it all summer.
Also, rice or couscous(better tasting than rice IMO) with tuna, a fresh vegetable added to the mix and soy sauce. That's crazy good too.
Just remember to have a few spices with you while cooking, they add some flavour because it isn't your mom's meat loaf after all. Personnaly, I like chilli and five colour pepper with a grinder.
And remember to not eat too much ramen noodles as a meal, they can be ok for a snack but I find them pretty sketchy to eat as a meal too often(once in a while, DAMN it's good).
My final words would be to drink a lot of water because these meals countains usually lots of salt and it's easy to get dehydrated.
Happy bumming or whatever cheap eating situation.
