I discovered this yumminess by accident one day when I ran out of room on the stove and tried to use the oven to saute my kale. I then forgot about it and this is the tweaked result.
Pre-heat oven to 350.
Lay kale in a single layer on a baking sheet (you may need to use 2 sheets).
Lightly spray both sides of the kale with the cooking spray.
Bake for 10-12 minutes.
Season with salt and pepper.
Enjoy the crunchy goodness!
