Ricky Martin's Beans

I decided to try and make one meatless meal a week and found this one on the website Meatless Monday. I thought, Ricky Martin's Beans, how can you go wrong?! :-) They actually were really good, similar to Mike's DR Beans.
2 tablespoons olive oil
1/2 cup chopped onion
1/4 cup chopped green bell pepper
2 garlic cloves, minced
1/4 cup tomato sauce
1/4 teaspoon dried oregano
1 can (15.5 ounces) small red kidney beans, drained and rinsed
6 cups hot, cooked white rice

In a large saucepan, heat oil over medium heat. Add onion, bell pepper, and garlic. Cook 5 minutes, stirring often. Stir in 3/4 cup water, tomato sauce, and oregano. Bring to a boil and stir in beans. Reduce heat to low, cover, and simmer 15 minutes, stirring occasionally. Serve beans over rice.
