simple vegetarian chili

1 (14oz) can fire-roasted tomatoes (Trader Joe's)
1/2 an onion, chopped
2 cans of beans (1 black, 1 garbanzo), rinsed
oregano
cumin
chili powder

Run the tomatoes through the blender to pulverize. This seems to help the consistency and flavor of the chili--it spreads the tomato taste through the chili better than individual chunks do. Saute onions in oil until browned on the edges. Add tomatoes. Cook a little. Add beans and spices to taste. Add a little water if needed. Cook on medium for a while, until you get bored. This tastes better with more cooking/the second day, and tastes oddly good with broccoli.

UPDATE: I often double this recipe and use a finely chopped green bell pepper (sauteed with the onion - generally added after it has sauteed a bit already) . Also I add a few cloves of garlic. Sometimes paprika. It's pretty good and pretty easy.
