1 jar sauerkraut, drained but not rinsed
8 oz. shredded mozarella
8 oz. shredded swiss
1/2 cup mayonaisse
1 lb. corned beef (I shred it or cut it into thin strips)
Mix together, spread in a 9x 13 inch pan, sprinkle a little cheese on the top and bake for 30 minutes at 350 degrees.
Serve with toasted party rye or pumpernickel slices.
