1Preheat oven to 400 degrees Fahrenheit. Move the rack to the middle position. Prep your peppers by cutting them in half and removing the seeds. You can keep the insides of the peppers and incorporate them into the filling.
2Using a 9×13 baking dish, pour 1 c. water in the bottom of the dish. This is to steam the peppers so they’ll cook faster.
3Heat oil in a skillet over medium-high heat. Sauté the onion and any chopped up pepper insides for 5 minutes.
4Add the sausage to the skillet and brown. Cook until the sausage is cooked through, roughly 8 minutes. Drain most of the fat.
5Stir in the diced tomatoes, rice and garlic. Season with salt & pepper.
6Fill your peppers. Once all the peppers are filled, cover the baking dish with foil. Bake for 40 minutes.
7After 40 minutes, remove the foil and sprinkle the peppers with cheddar cheese. Return to oven, uncovered, for another 5-10 minutes or until the cheese is bubbly and melted.
