Wash the bell peppers well. Cut off the tops and remove seeds inside. Keep the peppers whole. This helps hold the filling nicely. Set them aside while you prepare the filling.

Heat olive oil in a pan over medium heat. Add chopped onion and garlic. Cook until soft. Add ground meat and cook until brown. Stir well to break the meat into small pieces.

Now add cooked rice and tomato sauce into the pan. Mix everything well. Add salt, pepper, paprika and oregano. Cook for a few minutes so flavors blend nicely together.

Take each pepper and fill it with the prepared mixture. Press gently so filling stays inside. Place stuffed peppers in a baking dish standing upright.

Sprinkle shredded cheese over each stuffed pepper. This adds a rich and creamy taste. You can add more cheese if you like extra flavor.

Cover the baking dish with foil. Bake in a preheated oven at 180°C for 30 minutes. Then remove foil and bake for another 10 minutes until cheese melts.

Take the peppers out of the oven. Let them rest for a few minutes. This helps the filling settle and makes them easier to serve.

Serve warm and enjoy your delicious stuffed peppers. You can garnish with fresh herbs if you like. This dish tastes best when fresh.
