Massaging kale involves pouring a little oil or salad dressing over the kale and using your hands to massage the kale so that it softens. While you can massage kale, we find it's much easier to simply toss the salad and let the dressing sit on the kale for 5 minutes before eating it. The kale will be just as soft and easy to eat and you don't have to mess around with massaging kale.
