1/2 lb. bacon, cooked and crumbled
1/4 c. butter, melted
1/3 lb. whole fresh mushrooms
3 lg. eggs
2 c. milk

Place half the bread cubes in 1 1/2-quart casserole. layer half the cheese, bacon, and butter. Repeat layers and arrange mushrooms on top. Beat eggs, milk, mustard, and salt and pour over the layered mixture.

Set casserole in pan of hot water and bake uncovered at 300 degrees for 1 1/2 hours. This is better if prepared in advance and refrigerated overnight until baking time.
