Preheat the oven to 350 degrees.
Soak the bread in the milk for 15 minutes. Line the bottom of a 2 to 2 1/2 quart shallow casserole with a layer of bread soaked bread. Top with a layer of tomato sauce and mozzarella and some strips of ham. Continue layering, finishing last layer with bread topped with tomato sauce.
Beat the eggs with Parmesan and pour the mixture over the bread. With a fork, pierce through layers until egg mixture is absorbed by bread. Dot the top with butter and bake for 45 minutes or until top if browned and puffed.
While this is baking make a nice vegetable salad to accompany this dish.
