HELPFUL TIP: You can also layer the salad as indicated above without dressing or garnishing it. Cover with plastic wrap and refrigerate for 1 hour. The flavors of the beets and onions will marry better that way, but the onions will likely absorb some of the red color of the beets. Dress and garnish just before serving.You’ve noticed the citrus (orange) zest in the dressing. Orange and lemon zest both are great little tricks to keep up your “cook’s” sleeve if you want to enhance the flavor of a dish and cut back on your salt intake.
