01 - Set the oven to 375°F (190°C).
02 - Slice off the tops of the bell peppers and remove seeds and membranes. Set aside.
03 - Heat olive oil in a large skillet over medium heat. Add onion and cook for 2 to 3 minutes until softened. Add garlic and sauté for 30 seconds.
04 - Add ground beef or turkey to the skillet, breaking it up with a spoon. Cook until browned and cooked through. Drain excess fat if necessary.

06 - Incorporate shredded cheese into the filling mixture.
07 - Fill each bell pepper with the prepared meat and rice mixture, pressing gently to compact. Arrange peppers upright in a baking dish.
08 - Pour broth into the bottom of the baking dish to create steam during cooking.
