Let’s get cooking! Follow these simple steps to bring this dish to life:

1. Preheat your oven to 375°F (190°C).
2. Cut the tops off the bell peppers and remove the seeds. Lightly brush the outside with olive oil and place them in a baking dish.
3. In a large skillet over medium heat, add a drizzle of olive oil and sauté the onions until translucent. Add garlic and cook for another minute.
4. Add the ground beef or turkey to the skillet, breaking it apart with a spoon. Cook until browned, about 5-7 minutes.
5. Stir in the diced tomatoes, cooked rice, oregano, paprika, salt, and pepper. Let the mixture simmer for 5 minutes, allowing the flavors to meld together.
6. Stuff each bell pepper with the filling, packing it down gently. Top each pepper with a generous sprinkle of mozzarella cheese.
7. Cover the dish with foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.
8. Let them cool slightly before serving, and enjoy the comforting aroma that fills your kitchen.
