First, you want to preheat your oven to 425 degrees.
While your oven is preheating, begin making your rice by following the directions on the package.
Next, you will cut your peppers and remove the stems and seeds. Place the peppers cut side up in the baking dish. Roast the peppers for about 5-10 minutes. Once soft, remove them from the oven and remove the excess water with a towel.
While your peppers are roasting, make your sausage mixture. Start by cooking your Italian sausage in the saute pan over medium heat. Breaking up the sausage as it cooks. Once cooked, add your onion and garlic. Cook until the onion becomes soft.
Add your tomato paste, diced tomatoes, broth, parsley, and cooked rice. Season with salt and pepper.
Stuff your roasted peppers with the sausage mixture, top with mozzarella cheese, and bake until the cheese is melted, about 5-10 minutes.
Top with freshly grated parmesan cheese and serve immediately. Enjoy!
