- 1 teaspoon unsalted stick margarine
- 1 onion, chopped
- 1 1/2 cups low-sodium beef broth
- 2 ounces french bread, cut into two slices and toasted
- 1/3 cup shredded part-skim mozzarella cheese
Preheat the broiler. In a medium saucepan, melt the margarine. Add the onion and cook, stirring as needed, until softened, about 5 minutes. Add the broth; bring to a boil. Reduce the heat and simmer, uncovered, until the onion is very tender, about 3 minutes.
Place one slice of the toast in each of two flameproof soup bowls; pour the soup over the toast. Sprinkle each with the cheese and broil until the cheese is melted and lightly browned, about 1 minute. Serve at once.
