Impossibly Easy Onion Soup - cooking recipe

Ingredients

1 medium onion, chopped
1 teaspoon butter
1 tablespoon bovril powder
1 teaspoon Worcestershire sauce
1 cup boiling water
mozzarella cheese, grated
parmesan cheese, grated

Preparation

NOTE: the recipe calls for liquid bovril not powder bovril. I use Knoor bouillon concentrate. The computer did not recognize this ingredient, so please make this adjustment.
This recipe is for a single serving. For 2 people, double the recipe -- for 3 people, triple the recipe, etc.
Saute the onion in the butter until tender. Add bovril, worcestershire sauce and boiling water.
Simmer for 1/2 hour.
To serve: Sprinkle some parmesan cheese and serve ~or~ place soup in oven proof bowls. Shread a piece of french bread into the bowl. Grate some mozzarella cheese and add to the bowl. Sprinkle with parmesan cheese. Bake in 375 oven for 20 minutes or until cheese has melted.
