1 bag pre-washed kale*
2 tbsp olive oil
2 tsp white wine vinegar
Preheat oven to 350 degrees Fahrenheit and line two large baking sheets with parchment paper. In a large bowl, combine kale, olive oil, vinegar, and salt to taste.
Place the kale on the prepared baking sheets in a single layer. (A single layer is the key to crispy chips.) Bake for 15 minutes or until pieces are dry and crispy.
*I used pre-washed kale so that it is completely dry when I mix it with the oil and vinegar. If you have to wash yours, make sure to dry it in a salad spinner and then with paper towels or your chips will be soggy.
