  20      large         white mushrooms
     1/3  cup           onion -- diced
   2      tablespoons   cornflake crumbs
   2      tablespoons   bread crumbs -- fine
   2      tablespoons   parmesan cheese -- grated
   3      tablespoons   dry sherry
                        water
                        parsley flakes
                        salt and pepper
                        garlic powder (optional)

Preparation:

Wash and clean the mushrooms; then pull off the stems and dice. Place the diced stems and onions in a small bowl, and cover with wax paper. With the microwave on HIGH, cook for 45 seconds. Add the crumbs, cheese, sherry and enough water to moisten the mixture. Season to taste with parsley flakes, salt, pepper and garlic powder. Then spoon the filling into the mushroom caps. Place them around the edge of a large round microwave plate. Cook on MEDIUM for 3 minutes, turning the plate every minute for even cooking. Serve hot.
