Prepare Quinoa to package directions. Preheat oven to 375°F.

While quinoa is cooking prep your bell peppers, arrange in a 9x13" casserole dish, cut side up. I had pretty large peppers so I only needed 3, but if you have medium to small peppers you will need 4.

When quinoa is done, remove pan from stove. Add corn, black beans, tomatoes, chili powder, paprika, and cumin directly to quinoa in pan. Stir to combine until seasoning is fully incorporated. Taste mixture and add salt and pepper if desired.

Spoon equal amount of mixture into each prepared pepper until all mixture is used up. Tent dish with foil and place in oven for 30-45 minutes depending on how soft you want your peppers. We like ours very soft so I went with 45 min.

Remove from oven, carefully uncover, top peppers with 1/4-1/3 cup shredded cheese each (amount per pepper depends on if you used 3 or 4). Return dish to oven uncovered, bake 10 more minutes or until cheese is melted and bubbly. Remove, let rest for 5 minutes and serve. Top with sour cream, salsa and/or guacamole if desired.
