Making Easy Stuffed Bell Peppers is straightforward when you follow these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).

2. Prepare Peppers: Cut the tops off the bell peppers and remove the seeds and membranes. If needed, trim the bottoms slightly to help them stand upright.

3. Cook Meat: In a large skillet over medium heat, heat olive oil. Add chopped onion and cook until translucent, about 5 minutes.

4. Add Garlic: Stir in minced garlic and continue cooking for another minute until fragrant.

5. Brown the Meat: Add the ground beef or turkey to the skillet. Cook until browned and fully cooked, breaking it apart as it cooks, for about 7-10 minutes.

6. Combine Ingredients: Once the meat is cooked, drain excess fat if necessary. Stir in the cooked rice, diced tomatoes (with juices), oregano, salt, and pepper. Mix well to combine.

7. Stuff Peppers: Spoon the meat and rice mixture into each bell pepper, packing it tightly. Place the stuffed peppers upright in a baking dish.

8. Add Cheese: Top each stuffed pepper with a generous amount of shredded cheese.

9. Bake: Pour a small amount of water (about 1/4 cup) into the bottom of the baking dish to help steam the peppers. Cover the dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and slightly golden.

10. Garnish and Serve: Remove the dish from the oven and let cool for a few minutes. Sprinkle with fresh parsley if desired before serving.
