Italian Stuffed Mushrooms

Cook Italian sausage, onion, green pepper, garlic powder, and a handful of mushroom stems, finely chopped, in a skillet, then drain fat. (It's best if you put meat mixture into a food processor with steel blade at this point to give meat a finer texture. Just process for about 5 seconds or less.) Then add bread crumbs, pepper, salt, and spaghetti sauce. Coat mushroom caps with oil. Fill mushroom caps with meat mixture. Cover with foil and bake at 350 about 20 minutes. Sprinkle with mozzarella cheese, then broil until cheese is melted and mushrooms are tender. (Or loosely cover with wax paper and microwave.)
