For an extra layer of flavor, try adding a pinch of red pepper flakes to the dressing. Feel free to substitute other types of cheese, such as mozzarella or fontina, for the provolone. If you prefer a sweeter dressing, add a little more sugar or a touch of honey. This salad is best served chilled. Allow it to sit in the refrigerator for at least 30 minutes before serving to allow the flavors to meld.
