01 - Preheat the oven to 375°F. Cut the tops off the bell peppers and remove the seeds and membranes. Set peppers aside.
02 - Heat olive oil in a large skillet over medium heat. Sauté chopped onion and minced garlic for 2 to 3 minutes until softened.
03 - Add ground turkey to the skillet, breaking it up with a spoon. Cook for 6 to 8 minutes until browned and fully cooked through.
04 - Stir in diced tomatoes, cooked rice, dried oregano, paprika, salt, and black pepper. Cook for 2 to 3 minutes to blend flavors, then remove from heat and mix in chopped parsley.
05 - Fill each bell pepper with the turkey and rice mixture. Stand peppers upright in a baking dish.
06 - Optionally, sprinkle shredded cheese evenly over the tops of the stuffed peppers.
07 - Pour approximately ¼ cup of water into the bottom of the baking dish. Cover loosely with aluminum foil.
08 - Bake covered for 30 minutes, then remove foil and bake an additional 10 minutes until peppers are tender and cheese is melted and golden.
09 - Sprinkle extra chopped parsley on the peppers before serving.
