| Remove stems from mushrooms and chop finely. Set aside. Heat oil in a large skillet, cook onion and ground beef until lightly browned. Break up beef chunks until mixture is very fine, otherwise the stuffing tends to fall out of the mushrooms! Add the chopped mushroom stems, Worcestershire sauce, garlic powder and salt to onion-beef mixture and cook five minutes. Stuff mixture into mushroom caps, sprinkle with cheese.( This much can be done ahead and mushrooms set on broiler pan). Just before serving, preheat broiler and broil caps about 3-4 minutes. Serve hot with lots of napkins! *You can also use nonfat cheddar cheese product but be sure to watch your cooking process as this cheese burns easily. |
