Carefully slice the tops off the bell peppers and remove the seeds and membranes. Set aside.
In a skillet over medium heat, sauté the ground turkey or beef until fully cooked, breaking it apart with a spoon. Drain excess fat if necessary.
Add the taco seasoning to the meat along with the canned diced tomatoes (with their juices), cooked quinoa or rice, black beans, and corn. Stir until everything is well combined and heated through.
Once the filling is mixed together, take each bell pepper and stuff it with the taco mixture, pressing it down gently to fit as much filling as possible.
Place the stuffed peppers upright in a baking dish. If they are wobbling, you can slice a bit off the bottom to make a flatter base.
Sprinkle the top of each stuffed pepper with shredded cheese.
Cover the baking dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes, or until the peppers are tender and the cheese is bubbly and golden.
Carefully remove from the oven and let them cool for a few minutes before serving.
Top with fresh cilantro and a dollop of sour cream or Greek yogurt if desired.
