Although we are "only" vegetarian, we also have to deal woth a small budget most of the time !
I suggest you to try what I call a "chili con carne without carne"
. It's a bit hot now to test it, but it's lovely for cold evenings. It's a very simple recipe, but long to cook.
Use canned red beans, corn and tomatoes (if you don't have fresh ones just use canned ones again), and a lot of garlic and onions. Fry garlic and onions in olive oil, add the tomatoes, corn and beans and let it stew for at least one hour. A quarter before the end, add chili special spices (sweet chili, cinamon, cumin, paprika, ginger, and clove) and cocoa. When it's done, eat it in tortillas whit a salad leaf.
It's very good reheated too ! So you can prepare a lot of it and freeze it.
If you need more details just write me.
Sorry for my english, I've never writen an english recipe before...
