Directions
Saute onions in butter in a heavy 6-cup saucepot until golden brown, stirring often. Add water, bouillon cubes, pepper, salt if needed, and garlic powder. Bring to a boil and simmer, covered, 10-15 minutes. Add sherry and cook 2 minutes longer. Serve topped with French bread and Mozzarella cheese. Place under broiler long enough to melt cheese.
