A fresh and crunchy kale and apple salad is a great addition to your list of kale side dishes. Massage chopped kale leaves with a little olive oil to soften them. Add thinly sliced apples, some chopped walnuts, and dried cranberries. Toss everything together with a light vinaigrette made of olive oil, lemon juice, honey, and mustard. This salad is refreshing and full of flavor, perfect for any occasion.
