01 - Set the oven temperature to 375°F (190°C) to prepare for baking.
02 - Slice off the tops of the bell peppers and remove the seeds and membranes. Set aside.
03 - Heat olive oil in a large skillet over medium heat. Add the chopped onion and minced garlic, sautéing for 2 to 3 minutes until softened.
04 - Add ground turkey to the skillet, breaking it up with a spoon. Cook for 6 to 8 minutes until browned and fully cooked.
05 - Stir in diced tomatoes, cooked rice, oregano, paprika, salt, and black pepper. Cook for 2 to 3 minutes to meld flavors, then remove from heat and fold in chopped parsley.
06 - Fill each bell pepper with the turkey and rice mixture, arranging them upright in a baking dish.
07 - Optionally, sprinkle shredded cheese over the stuffed peppers for added richness.
08 - Pour approximately 1/4 cup water into the bottom of the baking dish and loosely cover with aluminum foil.
09 - Bake covered for 30 minutes. Remove the foil and continue baking for an additional 10 minutes until peppers are tender and cheese has melted and browned.
10 - Sprinkle extra chopped parsley over the peppers before serving.
