2. Cut the top off the bell pepper and remove the seeds.
3. In a bowl, mix the cooked quinoa, black beans, diced tomatoes, corn, cumin, paprika, salt, and pepper until well combined.
4. Stuff the mixture into the hollowed bell pepper, packing it tightly.
5. If using, sprinkle the shredded cheese on top of the stuffed pepper.
6. Place the stuffed pepper in a baking dish and pour a little water into the bottom to create steam.
7. Cover the dish with foil and bake for 25 minutes.
8. Remove the foil and bake for an additional 10 minutes, until the pepper is tender and the cheese is melted.
