This shaved apple salad is made with tart Granny Smith apples, and savory ingredients to make the perfect combination for sandwiches, or burgers. Granny Smith apples work great in a slaw or salad because they are firm and hold their shape longer than some other apples. Capers are reminiscent of the lemony tang and brininess of green olives, but with a floral tartness. They are great when added to salads.
