For an enhanced flavor, consider roasting the garlic cloves along with the beets. Simply wrap them in foil with the beets. If you prefer a sweeter dressing, add a teaspoon of honey or maple syrup. Toasted walnuts or pecans add a delightful crunch to this salad. Sprinkle them on just before serving. The dressing can be made a day in advance and stored in the refrigerator. This allows the flavors to meld together beautifully. Feel free to substitute other types of lettuce, such as butter lettuce or romaine, if red leaf lettuce is unavailable.
