Start by preheating your oven to 375°F (190°C) to ensure it's hot enough for baking.
Prepare the bell peppers: Cut off the tops and carefully remove the seeds and membranes. Drizzle the olive oil over the outside of each pepper and then season with salt and pepper. Stand them upright in a baking dish to hold their shape.
In a large skillet over medium heat, add the ground turkey or beef. Cook, stirring occasionally and breaking it into pieces, until the meat is browned and fully cooked—about 5-7 minutes. Drain any excess fat from the skillet if necessary.
To the skillet with the cooked meat, stir in the taco seasoning thoroughly, followed by the cooked rice, rinsed black beans, corn, and half of the salsa. Mix well and continue cooking for another 3-4 minutes, allowing all the ingredients to heat through and meld flavors.
Carefully spoon the hearty taco filling into each bell pepper, making sure to pack it tightly for maximum flavor. Drizzle the remaining salsa generously over the top of all the stuffed peppers.
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for about 25 minutes.
After 25 minutes, remove the foil and sprinkle the shredded cheese over the tops of the stuffed peppers. Return the dish to the oven and bake uncovered for an additional 10 minutes, or until the cheese is melted, bubbling, and slightly golden.
Remove the stuffed peppers from the oven and allow them to cool for a few minutes. Before serving, garnish with freshly chopped cilantro or parsley to add a refreshing touch.
