Preparation

Step 1

In a large saucepan, cook onions in butter until tender but not brown. Add beef broth, sherry, Worcestershire sauce and pepper and bring to a boil. Pour into individual ovenproof bowls. Float a slice of toasted French bread in each. Sprinkle with Parmesan and top with mozzarella. Place under broiler and heat until cheese bubbles. Scrumptious!
