Creating Easy Stuffed Bell Peppers with Ground Beef and Rice is straightforward when you follow these steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C) to prepare for baking the stuffed peppers.
2. Prepare the Peppers: Slice the tops off the bell peppers and remove the seeds and membranes. Set aside.
3. Cook the Meat: In a large skillet, heat olive oil over medium heat. Add the chopped onion and garlic; sauté until softened (about 3-4 minutes).
4. Add Ground Beef: Stir in the ground beef, cooking until browned and cooked through. Drain excess fat if needed.
5. Combine Ingredients: In the skillet with the cooked beef, add the cooked rice, diced tomatoes, Italian seasoning, salt, and pepper. Mix well until everything is evenly combined.
6. Stuff the Peppers: Spoon the beef and rice mixture into each bell pepper until they are generously filled.
7. Top with Cheese: Place the stuffed peppers in a baking dish, and sprinkle shredded cheese on top of each one.
8. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 25-30 minutes. Remove the foil and bake for an additional 5-10 minutes, or until the cheese is bubbly and golden.
9. Garnish: Once cooked, take the peppers out of the oven and let them cool for a few minutes. Optionally, garnish with fresh herbs before serving.
