Creating stuffed peppers is straightforward when you follow these steps:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C). This ensures the peppers cook evenly.
2. Prepare the Peppers: Cut the tops off the bell peppers and remove the seeds and membranes. Rinse them under cold water and set aside.
3. Cook the Filling: In a large skillet, heat a bit of oil over medium heat. Add the chopped onion and garlic; sauté until the onion becomes translucent.
4. Add the Meat: Incorporate the ground meat into the skillet and cook until browned. Break it apart with a spoon to ensure even cooking.
5. Mix in Other Ingredients: Add the diced tomatoes, cooked rice, Italian seasoning, salt, and pepper. Stir to combine everything thoroughly. Let it simmer for a few minutes.
6. Stuff the Peppers: Carefully fill each pepper with the prepared mixture, packing it in gently but firmly.
7. Add Cheese: Top each stuffed pepper with shredded cheese to add deliciousness.
8. Bake: Place the stuffed peppers in a baking dish and cover with aluminum foil. Bake for 30 minutes, then remove the foil and bake for an additional 5-10 minutes, or until the cheese is bubbly and slightly golden.
9. Cool and Serve: Once done, let the peppers cool for a few minutes before serving. Garnish with fresh parsley if desired.

These steps will help you create mouthwatering stuffed peppers that are sure to please everyone at your table.
