4 pounds fresh mushrooms, broken end to end and stems removed
2, green onions and ½ cup chopped onions
2 teaspoons salt
2 teaspoons ground black pepper
6 slices mozzarella cheese
Press mushrooms into pan, turning them over at intervals so you make filling compact. Bolt mushrooms with oil in a moderate skillet. Heat generously on medium heat.
Place onions in mushrooms, around stem and half. Cook over medium flame until golden, then reduce heat. Trim sides of onions, leaving about 2 inches on stem ends. Place mushrooms in pan with filling.
Place mozzarella cheese in same pan. Transfer with 1 teaspoon glaze to skillet. Transfer filling between two prepared plates.
Spread marinated mixture evenly over mushrooms. Return mushrooms to skillet. Cover pan with aluminum foil. Close lid. Broil over medium heat until cheese has melted, about 30, stirring occasionally. Serve.
