Slice or dice beets.Toss with vinagrette sauce to coat well. Let stand--at least 10 minutes, or as long as overnight--refrigerated, to develop flavor. Sprinkle on the cheese and nuts just before serving.
TIP: If using homemade vinaigrette, see recipe for Lemon Vinaigrette for a sauce that complements the beets nicely. For beet roasting directions, see recipe for Beet and Apple Salad.
