Wash and dry bell peppers. Slice off top of bell pepper, just below the stem. Set aside tops and place peppers in baking dish sprayed with non-stick spray.
Dice up tops of peppers, discarding stems.
Brown sausage, onions, diced pepper tops, and garlic in a skillet over medium-high heat.
Meanwhile, cook rice per package instructions.
When sausage is no longer pink, add meat mixture to rice in saucepan. Stir to incorporate.
Season mixture with salt, pepper, and Italian seasoning.
Spoon into peppers, until mixture is to the top of each pepper.
Bake in the oven for 30-40 minutes until peppers are crisp-tender.
Remove from oven and sprinkle 1 ounce of cheese on top of each pepper. Return to oven and bake for an additional 5 minutes.
Notes
If you prefer more tender peppers, bake unstuffed peppers for 10 minutes prior to stuffing.
