Rice and Bean Casserole

I found this on back of a cheese bag. We had it and it was a nice, easy meatless dinner.

Rice and Bean Casserole
1 small onion, chopped
1 tbsp oil (I used olive oil)
1 tsp chopped garlic
1 tsp oregano
3/4 tsp cumin
1 can (15oz.) diced tomatoes (I pureed them in my processer so my kids wouldn't complain)
1 can balck beans, rinsed and drained.
1 cup rice, uncooked
2 cups shredded colby jack cheese

In large skillet sauted onion in oil. Add garlic, oregano, cumin, tomatoes, and beans to onion. Cover and cook on med. heat. Cook rice according to package. Add rice and mix well. Then add cheese and mix well until cheese has melted. Serve with tortilla chips. (we just dipped our chips in and enjoyed)
