Asparagus Ham Strata

Using a doughnut cutter, cut 12 circles and holes from bread; set aside. Tear remaining bread in pieces and place in a greased 13-in. x 9-in. baking dish.

Layer with cheese, asparagus and ham; arrange bread circles and holes on top. Lightly beat eggs with milk.

Add onion, salt and mustard; mix well.

Pour egg mixture over bread circles and holes. Cover and refrigerate at least 6 hours or overnight.

Bake, uncovered, at 325° for 55 minutes or until top is light golden brown.

Let stand for 10 minutes before serving.
