At our farmer's market they sell "kale chips". I have never tried them. I do not need to because I do not like potato chips. The only crisp food that I like is Finnish rye crackers, at 20 calories per piece. But if kale chips work to substitute for potato chips (I do not know if they do but the kale chips stall is pretty busy), then it is a smart solution. Instead of applying willpower and saying no to chips while continuing to want the crisp texture, satisfy the want by eating healthful chips. Kale is a nutritional powerhouse, unlike peeled potatoes.
