3 large sweet onions or 4 medium white or yellow onions
2 c. shredded Swiss cheese (8 oz.)
1 can cream of mushroom soup, undiluted
2/3 c. milk
1 tsp. soy sauce
8 or so slices of French bread
Slice onions. Melt butter in a saute pan over medium heat, and add onions. Saute onions until clear. In a shallow 2 qt. casserole pan, layer onions, 2/3 of cheese and pepper to taste. In a sauce pan, heat soup, milk, and soy sauce, stirring to blend. Pour soup mixture in a casserole and stir gently to mix. Top with bread slices. Bake at 350 uncovered for 15 minutes. After 15 minutes, top of bread should be nice and toasted.
Push bread slices under the sauce and top with the remaining cheese. Place casserole back in oven and finish baking for 15 more minutes.
