1 bunch of kale, try to get those with flatter leaves for a crispier texture
1 tablespoon olive oil
salt and pepper to taste
Preheat oven to 300F.
Wash kale and dry thoroughly.
Remove the center stem and chop leaves into 3-inch pieces.
Toss with olive oil in a large bowl. Sprinkle with salt and pepper and toss again to coat.
Arrange leaves in a single layer on a baking sheet, and bake for 20 minutes, until completely crisp.
Turn the kale half way through. Watch carefully to make sure that the chips do not burn.
