Ingredients

1/4 Cup butter
2 medium onions, sliced and separated into rings
2 Tablespoon flour
2 10 1/2-ounce cans beef broth
2 1/2 Cup water
6 Slice French bread (1-inch thick), toasted
1 Package Mozzarella cheese, shredded

Instructions

In a 2-quart microwave-safe dish, melt butter; then stir in onion rings. Cover and cook on high for 10 to 12 minutes, or until onions are soft. Stir halfway through cooking time. Stir in flour, broth and water. Cover and cook 10-15 minutes more. Place a slice of toasted bread in each of six microwave-safe bowls. Ladle soup over bread and sprinkle with cheese. Microwave just long enough to melt the cheese.
