Reuben casserole is a great way to use up leftover corned beef or to make a quick weeknight meal using pastrami from the deli. It has all the flavor of a Reuben sandwich, but very little hands-on time. Just mix it together, and pop it in the oven!
Ingredients:
Butter for the baking dish
8 slices (9 ounces) seeded sliced rye bread
1 1/2 pounds sliced pastrami or corned beef (from the deli or homemade)
