1 1/2 lbs. onion, thinly sliced
1/4 c. butter
3 (10 1/2 oz.) cans condensed beef broth
1 tsp. Worcestershire sauce
1/4 tsp. salt
6 to 8 slices French bread or hard rolls, toasted
Grated Parmesan cheese

In a covered 3 quart saucepan cook sliced onions in butter about 20 minutes or until tender. Add beef broth, Worcestershire sauce, salt and pepper. Bring to boiling.

Sprinkle toast slices with grated Parmesan cheese, place under broiler until cheese is lightly browned. Ladle soup into bowls and float toast slices atop. (Or, place a toast slice on soup in each broiler- proof soup bowl; sprinkle with Parmesan cheese and place bowls under broiler until cheese is lightly browned.) Makes 6 to 8 servings.
