Edit: broke, pseudo adults.

I've been living on my own for a few months now and I feel like I have no idea what to eat. I mean my life is a tornado of poverty. but some times I can blow some decent cash at the grocery store but I never know what to buy.

I like cooking but I don't know much about cooking and when I lived with my dad I just ate like an asshole all the time(fast food, takeout and bad frozen shit) now I'm on my own, with my culinarily inept girlfriend, and I fancy myself to be a foodie. Cooking pleases me. but I don't know what to make. when I'm broke I eat ramen and crappy frozen dinners. and when I've got cash I eat chilli and SPAM. Sometimes I make Bacon, eggs and pancakes for breakfast but thats one of the most in depth things I get to do.

basically I'm wondering if theres some kind of guide for people like me out there who like to eat well but don't have alot of money.

I just want to cook a variety of good things using simple and cheap ingredients.
