Rip kale into small pieces and remove hard spines Add kale to air fryer, spray with oil and shake basket to coat Add chili powder, salt and pepper. I like to do this while the kale is "wet" from the oil so it sticks. "Fry" kale at 375 degrees for about 6-7 minutes or until desired texture is reached. *Remember to shake basket every couple minutes to avoid kale getting stuck in the vent) Add to a plate and season with more chili powder if desired.
