Spread butter on one side of each slice of bread. Place four slices butter side down in a greased 13-in. x 9-in. baking dish. Top with American cheese, ham and Parmesan. Top with remaining bread, butter side up.
In a large bowl, whisk the eggs, milk and seasonings. Pour over bread; turn each sandwich. Bake, uncovered, at 350° for 30-35 minutes or until golden brown. Yield: 4 servings.
