"A family favorite! The amounts listed are only a guideline you may adjust to taste, make certain that the cheese is always on the top, this is a great way to use up cooked roast beef or deli roast beef. FOR PARTY APPETIZERS instead of using buns replace with small party size pumpernickle bread slices that have been toasted, follow as directed only using smaller amounts"

This is a great way to use up left over roast beef. I made one with provolone for DH and one with a non dairy cheese slice for myself. Delicious!!!
