1 large bunch of kale
Extra-virgin olive oil
Sea salt or kosher salt
Preheat the oven to 300°. Thoroughly wash and dry the kale. Using a knife or kitchen shears, remove the tough stems and center ribs from the kale. Chop the leaves into bite size pieces.
Line two baking sheets with parchment paper (for easier clean-up). Place the kale on the baking sheets and lightly drizzle with olive oil. Gently toss to coat. Spread the kale in an even layer and sprinkle salt over the top.
Bake for 20 minutes or until crisp. Sprinkle with additional salt to taste.
