Buttery Grilled Onions Recipe

Carefully remove a 1-in. x 1-in. core from the center of each onion (save removed onion for another use). Place each onion on a double thickness of heavy-duty foil (about 12 in. square). Combine the butter, bouillon, garlic powder and pepper; spoon into onions. Sprinkle with sherry if desired. Fold foil around onions and seal tightly. Grill, covered, over medium heat for 30-40 minutes or until tender. Carefully unwrap foil to allow steam to escape. Sprinkle onions with Parmesan cheese. Yield: 6 servings.
