Second Time Around Beef Salad
Toss the beef with as much horseradish mayonnaise as you like to season and moisten the beef. If you have no mayonnaise leftover, then toss with a vinaigrette to which you add mustard and some horseradish. Fold in the peppers and season to taste with salt and pepper. Center the beef on a bed of watercress or arugula leaves lightly tossed with olive oil.
