For a nutrient-rich chip, grab yourself a bunch of kale. Kale chips are light, crispy, nutty, and as you'll find out — totally addictive. They're also light on calories. Chips made from half a bunch of kale are only 59 calories, but packed with vitamins A and C, calcium, and iron. I bet a bag of Lay's or Ruffles can't boast the same.
