Italian-style Stuffed Peppers On large microwave-safe platter, place green peppers upside-down, stacking if necessary. Pour õ cup water beneath and cover with plastic wrap. Heat on HIGH 10 minutes. While peppers are steaming, bring remaining water with oil to a boil in a large saucepan with a tight-fitting lid. Reduce heat and stir in rice. Cover and allow to steam for 20 minutes. Remove peppers and align right side up on large baking dish, set aside. Preheat oven to 350F. Combine rice and meat mixture in a very large bowl. Fill peppers with meat and rice mixture, cover with sauce and top with cheese. Fill up rest of the room in the tray with remaining mixture top with sauce and cheese as well. Bake for 10-15 minutes, or until cheese has browned. Serve peppers with extra mixture surrounding them.
