Breaded Leftover Roast Beef Slices with Dijonnaise

Prepared with thin slices of cooked roast beef, these cutlets are a tasty way to use up leftovers for the next evening’s meal. Serve with a side of boiled new potatoes and steamed broccoli or on a crusty roll with lettuce, tomato and shaved red onion. You could also make this with raw fast-fry steaks or thicker-cut cooked roast beef, if preferred. Cut the recipe in half if you don’t have a full pound of leftover roast beef.
