Happy St. Patrick's Day - Reuben Casserole

This is a really easy casserole that can be quickly thrown together.  We really enjoyed this casserole which is perfect for St. Patrick's Day.  I made corned beef and cabbage a couple of days before making this and used the leftover corned beef to make this recipe.  Delicious!
