6 oz kale, chopped
1 tbsp olive oil
1. Preheat oven to 300°F. Rinse and drain the leaves, then remove the stems and any tough center ribs (I lay the leaves flat on a cutting board and remove the stem and rib with a couple of knife cuts run lengthways along the leaf).
2. Next, cut the leaves into large pieces (2-3″), and toss them with the olive oil in a large bowl until the pieces are all coated with oil. Sprinkle with salt if desired (we usually leave ours unsalted).
3. Line a baking sheet with foil or parchment paper for easier cleanup. Arrange the kale pieces in a single layer on the baking sheet.
4. Bake for 15-20 minutes until crisp, then let baking sheet cool on a rack before removing chips.
