• Preheat oven to 350 F. Rinse the kale and pat dry with a paper towel. Cut off stems and tear leafs off of the rib. Throw away the center rib pieces and set aside.
• In a large bowl whisk together oil, vinegar and salt and add the kale. Gently toss together.
• Line two baking sheets with parchment paper and divide kale among them. Bake for 10-15 minutes or until crispy, flipping halfway through.
