2 c. cubed decrusted bread
1/2 lb. sharp cheddar cheese
1/2 stick melted butter
1 c. cubed ham (or shrimp)
2 c. milk
3 eggs
1 tsp. salt
1 tsp. dry mustard
4 1/2 oz. sliced canned mushrooms

Make 2 layers as follows:

Layer of cubed bread into oiled casserole. Pour over the bread 1/2 of melted butter then sprinkle ham, cheese and butter. Beat eggs and add to eggs, milk, seasonings and mushrooms. (Be sure that it's all moist). Refrigerate overnight.

To cook: Place casserole in pan of water and bake at 300 degrees for 1 1/2 hours. (I had some leftover heavy cream so before I put it in the oven I added about 1/4 cup.)
