Combine orzo, broth, enchilada sauce, corn, beans, and seasonings in a large nonstick (or well-greased) pot and sitr to combine. Cover and cook over medium-low heat 20-25 minutes, until liquid is absorbed and orzo is tender.
Uncover, stir, and sprinkle cheese over the top. Cover again and allow to cook 1-2 minutes until cheese is melted. Add any desired toppings and serve.
