Preheat your oven to 375°F (190°C) to ensure it's hot and ready.
Carefully slice the tops off the bell peppers and remove the seeds and membranes inside. Set the cleaned peppers aside.
In a skillet over medium heat, add the ground turkey or beef. Cook thoroughly, breaking the meat apart with a spatula until no longer pink. Drain any excess fat if needed.
Sprinkle the taco seasoning over the cooked meat, then pour in the diced tomatoes (with their juices), cooked quinoa or rice, black beans, and corn. Stir everything together until well combined and heated through, about 3-5 minutes.
Once the filling is ready, take each bell pepper and gently stuff it with the taco mixture, pressing down firmly to maximize the amount of filling inside.
Arrange the stuffed peppers upright in a baking dish. If they seem unstable, slice a thin edge off the base to make them sit flat.
Evenly distribute the shredded cheese on top of each stuffed pepper, ensuring full coverage.
Cover the baking dish with aluminum foil to help retain moisture, and bake in the preheated oven for 25 minutes. After this, remove the foil and bake for an additional 15 minutes, or until the peppers are tender and the cheese has melted and turned golden brown.
Once baked, carefully remove the dish from the oven and let the peppers cool for a few minutes before serving to prevent burns.
Garnish the top of each stuffed pepper with freshly chopped cilantro and add a dollop of sour cream or Greek yogurt for a delicious creamy finish.
