1/2 cup dried mushrooms, chopped into small pieces
1 cup strong broth
1 small onion, diced
2 Tbs. flour
1 1/2 Tbs. margarine
Hydrate your chopped mushrooms with about 1/2 cup boiling water. Cover and let sit for 10 minutes.
Melt margarine in a small-medium saucepan over medium heat. Sauté the onion lightly. Dont brown too much. Add the flour, and stir constantly with a wooden spoon until frothy. Do not let it burn! Add the mushrooms and their liquid and your vegetable broth. Cook over medium heat to a boil, stirring constantly. After it comes to a boil, turn the heat down a bit and let thicken.
