DIRECTIONS
In a large skillet, saute onions in 2 tablespoons butter until tender. Sprinkle with flour; stir in salt and pepper. Add the consomme and sherry if desired; cook and stir until thickened, about 3 minutes. Pour into a shallow 2-qt. baking dish or individual baking dishes. Spread remaining butter on both sides of bread; place on a baking sheet. Bake at 350° for 10-15 minutes or until golden brown. Place bread on top of onion mixture; sprinkle with cheeses. Bake, uncovered, for 10-15 minutes or until cheese is melted and bubbly. Yield: 4 servings.
