1 can (10-3/4 ounces) condensed cream of chicken soup, undiluted
2/3 cup whole milk
1 teaspoon soy sauce
8 slices French bread, buttered on both sides
In a large skillet, melt butter. Saute onions until translucent and slightly brown. Layer onions and two-thirds of the cheese in a 2-qt. baking dish, sprinkling pepper between layers.
In a saucepan, heat soup, milk and soy sauce; stir to blend. Pour over onions and stir gently. Top with bread. Bake, uncovered, at 350° for 15 minutes. Push bread under sauce; sprinkle with remaining cheese. Bake 15 minutes longer.
