Preheat the oven to 375°F (190°C).

Cut the tops off the bell peppers and remove the seeds.

In a skillet over medium heat, cook the sausage until browned.

Add cooked rice, tomato sauce, Italian seasoning, garlic powder, onion powder, salt, and pepper to the skillet. Mix well.

Stir in half of the shredded cheese.

Stuff the mixture into the prepared bell peppers.

Place the stuffed peppers in a baking dish and top with remaining tomato sauce and cheese.

Cover with foil and bake for 25 minutes, then remove the foil and bake for an additional 5 minutes until cheese is bubbly.
