Cook your rice according to instructions (I used a rice cooker) You will need 4 cups of cooked rice to add to the recipe
While your rice is cooking, heat a large heavy bottomed pan over medium high heat (I used a dutch oven, but any large pot or deep skillet is fine to use)
Add 1 tablespoon of olive oil, and sauté the red onion, garlic, and bell pepper for 8-12 minutes, until the onion softens
Add the corn and fire roasted tomatoes and stir an additional 3 minutes
Add the drained black beans, cooked rice, lime juice, enchilada sauce, chili powder, cumin, cayenne, cream cheese, and 1/2 cup of the mexican cheese
Stir the casserole and salt to taste (I used 1 teaspoon of salt)
Serve hot topped with additional mexican cheese, sour cream, and tortilla chips
