theyre SO easy and have a crisp if you like that kinda thing. they dont replace chips, but they def are a good substitute! you can put any seasoning on them, i usually make a bbq one, reg sea salt, or i really like nutritional yeast. its great for a cheesy/nutty flavor! you just massage the kale with a litte evoo and bake. heres the directions i usually use!
