1. Preheat oven to broil.
2. Remove the stiff stalks from the kale leaves and tear each leaf into small pieces (like you would for a salad).
3. In a large bowl, toss the kale leaves with olive oil, salt, pepper, and any other spices you like (garlic is a nice touch), making sure the kale is coated evenly with oil.
4. Spread the kale evenly on a parchment lined baking sheet and place under the broiler. Watch it closely! In a minute or two, the kale will start to brown just a tad. Take it out and stir it around, turning it over so it can crisp on the other side. Place under the broiler again.
5. When the kale is evenly crispy, pile it in a bowl and gobble it up. Taylor and I can polish off a whole head between the two of us, easily. So tasty :)
