Have you tried Baked Kale yet?
It is surprisingly crunchy, salty, and even a bit nutty
You can buy the Kale loose or by the bag
I have done both and like the bag option better
The kale seems to be crisper which is better for baking
Arrange your Kale on your cookie sheet
Coat with Olive oil and salt
Bake at 300* for 20 minutes
