Cook rice to box specifications and heat oven to 350.
Sautee the onion, garlic and green pepper in some olive oil. Tear up tortillas into large 4 inch (or so) sized chunks and place on bottom of baking dish. (I use a round 11 inch, 6 cup volume dish)
Spread beans onto tortillas. In a separate bowl mix the cooked rice with some soy cheese, the can of tomatoes and the sauteed onion/garlic/green pepper. If you want an extra kick add the chilies. Add salt and pepper while mixing- I also add a little oregano.
Spread this mixture over the beans. Top with more soy cheese. Bake approximately 20 minutes.
