Take your Corned beef and wrap it in tinfoil and place in oven at 300 for 10 minutes. You want to "steam it" not microwave it
In a pan toast your buttered rye bread (marble preferred) toast both sides in pan.
Spread Keens mustard on both halves.
A slice of Provolone or Swiss cheese
(If you want a Rubin a layer of Saurkraut)
Fill sandwich with steamed corned beef
Serve with a pickle and your favorite soup
Enjoy!!
