I made a pot of vegetarian chili last night. It came out pretty good. I don't measure anything when I cook but I can tell you the basics.
I used one large can of stewed tomatoes and one large can of diced tomatoes. I added one chopped onion, a can of kidney beans, one large bell pepper, and one diced zucchini.
I added the spices; salt, pepper, cayenne, chili powder, garlic powder, onion powder, and cumin.
I raised it to a boil then burned it down to simmer for about two hours. It was pretty tasty.
