3/4 lb. sharp cheddar and Swiss cheeses, grated (3/4 lb. in all)

Break bread into pieces the size of a quarter. Place half of the bread in a buttered 3-quart casserole. Over this spread in layers the mushrooms, olives and grated cheeses. Spread the remaining bread cubes over the top.

Beat the eggs; add milk and seasonings and pour over all. Refrigerate overnight. Bake uncovered for 1 hour at 350 degrees. Take from oven and let set for 10 minutes before serving. Serve with sausage or bacon, hot rolls or sweet rolls. Serves 8.
