Preheat oven to 325 degrees F. Wash and de-stem one bunch of kale. Break into “chip” size pieces and massage about a teaspoon of olive oil or avocado oil into the kale pieces. Spread out on a baking tray and sprinkle with sea salt. Bake at low heat, about 325 degrees for about 15-20 minutes. Watch carefully at the end so they don’t overcook, you just want them to be dry and crunch, not brown.
