Rosalie's Beans and Rice

My friend Rosalie made us beans and rice tonight, and it was delicious! Even my husband, who normally doesn't like beans and rice, loved them and had several servings.

Ingredients
olive oil
2 onions
2 or 3 cloves garlic
2 small cans tomato sauce
salt, pepper, chili powder
2 cans beans, undrained (we used black beans, but you can experiment)
2 cups dry rice

Directions

1. Slice the onion and chop the garlic. Saute in olive oil until the onion begins to brown and wilt a bit.
2. Add the tomato sauce and two cans of water. Season with salt, pepper and chili powder to taste. Bring to a boil, then simmer for 15 minutes or so. 
3. In another pan, cook the rice as usual.
4. Add the beans (with their juice) to the tomato sauce mixture. Stir and heat through.
5. Serve the bean mixture over the rice.
