5 1/4 cups vegetable broth, divided
4 onions, sliced
1/8 teaspoon white sugar
2 tablespoons all-purpose flour
1/2 cup dry white wine
1 bay leaf
1/2 teaspoon ground thyme
1/2 teaspoon ground black pepper
1 tablespoon brandy
4 slices French bread, toasted
1 clove garlic, halved
2 tablespoons grated fat-free Parmesan cheese
In a large non-stick saucepan, heat 1/4 cup vegetable broth. Stir in the onion and cook over medium heat until golden, 15 minutes.
Stir in the sugar and flour. Pour in the remaining 5 cups vegetable broth and the wine. Stir in the bay leaf, thyme and black pepper. Bring to a boil and let boil 8 minutes, stirring constantly; then reduce heat, partly cover, and simmer 30 minutes.
