Spicy Rice with Black Beans and Corn

This recipe evolved from an attempt to make a vegetarian dish with whatever ingredients I had around. Eventually I settled on the the ingredients listed below. It goes well as a side dish, main dish, or even as a burrito filling.

Sauté the onions, green pepper and garlic in a heavy large saucepan until tender. Drain the mushrooms and add them to the mix and sauté a few more minutes. Mix in the rice and brown a few more minutes. Add water, tomato sauce and remaing ingredients. Bring to a boil; cover and reduce heat. Simmer 15 to 20 minutes, or until the liquid is absorbed.
