<human>: I need a good recipe for a savory stuffed peppers.
<bot>: Preheat the oven to 350°F (175°C). Place the bell peppers on a baking sheet and roast until tender, about 20 minutes. Remove from oven and set aside. In a large bowl, combine the ground beef, onion, garlic, bread crumbs, parsley, salt, and pepper. Stuff each of the roasted bell peppers with the beef mixture and place them in a 9x13 inch baking dish. Pour the tomato sauce over the stuffed peppers and bake at 350°F (175°C) for 30 minutes. Serve hot with a sprinkle of Parmesan cheese. Enjoy!
