This recipe was invented by me and my roommates (one is South Indian and the other is half Cuban). I was very uncertain about how the flavors would mix, but it ended up being seriously tasty. We didn't measure anything, so everything is approximate.
1 onion, diced
2 or 3 tomatoes, diced
1 can of black beans, rinsed and drained
1 cup corn kernels (preferably fresh, but frozen is fine)
cumin to taste
2 chili peppers, sliced in half and seeded
coriander to taste
garam masala to taste
fresh cilantro, chopped
Saute onions in butter or vegetable oil until translucent. Add tomatoes, black beans, and corn, and simmer for several minutes. Add spices to taste. Remove from heat, let cool for a little while, and stir in cilantro. Serve with tortilla chips or bread.
