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.

Really outstanding. Lots of rich flavor without all of that fat filled gravy. The onion and tomato add a clean freshness and using low fat cheese allows for 2 or 3 extra slices of lean roast beef. I have loved the grainy mustard for a long time and it's a natural in this sandwich. :D
