Preheat an oven to 350 degrees F (175 degrees C). Line a non insulated cookie sheet with parchment paper.
With a knife or kitchen shears carefully remove the leaves from the thick stems and tear into bite size pieces. Or, you can purchase a bag of pre-cut, pre-washed kale and skip to step 4
Wash and thoroughly dry kale with a salad spinner. If you do not have a salad spinner, you can wash kale by hand with water only and pat dry with a paper towel or cloth.
Drizzle kale with olive oil and sprinkle with seasoning salt.
Bake until the edges brown but are not burnt, 10 to 15 minutes.
