Not a clear-broth type, but interesting.
5 onions, cut in half, then sliced thin
1/4 cup olive oil
3-4 cloves garlic, minced
3 tablespoons flour
1 teaspoon paprika
4-5 cups vegetable stock
1 tablespoon miso
1 tablespoon soy or tamari sauce
freshly ground salt and pepper
Sautee the onions in the olive oil over medium to medium-high heat, covered, until softened. Then remove cover and continue to sautee until lightly browned. In a small bowl, mix garlic, flour and paprika. Sprinkle over onions and mix. Slowly blend in vegetable stock; then add miso and soy/tamari sauce. Bring just to a boil, then reduce heat and simmer 30 minutes. Adjust seasonings with freshly ground salt and pepper. Serve with croutons and vegan cheese, if desired.
