Easy breakfast casserole

At one of our potluck days for the ladies' bowling league I'm in, one of the ladies brought this. It's one of those super easy make-the-night-before casseroles.

Sandwich bread (the square loaf works best) with crusts removed
12 eggs
1 1/2 cups milk
salt and pepper to taste
1/2 to 3/4 pound of sliced deli ham
About 8 cheese slices

Using a 9 X 13 pan, place slices of buttered bread in pan in a layer with the buttered side down. (No need to grease the pan.) Add a layer of ham and a layer of cheese and top with another layer of buttered bread, with the buttered side up. In a bowl, beat eggs and add salt and pepper. Pour over top of bread. Leave in refrigerator overnight and the next morning bake at 350 degrees for about 45 to 50 minutes.
