In a saucepan, bring water to a boil. Add rice and stir. Reduce heat, cover and simmer for 20 minutes.

While the rice is cooking, cook sausage in a large skillet over low heat for 5 minutes. Stir in onion, green pepper and garlic; saute until tender. Pour in beans and tomatoes with juice.

Season with oregano, salt and pepper.

Simmer uncovered for 20 minutes. Add additional water as needed. Serve over rice.
