Preheat oven (toaster oven works best) to 225F. Tear kale into pieces (uniformity is more important than size--but they shrink down so don't make the pieces too small). Place kale on a non-stick cookie sheet or a cookie sheet lined with parchment paper (they might stick to a regular cookie sheet). Sprinkle generously with spices such as sea salt, nutritional yeast, Old Bay seasoning (my fave), ground ginger, garlic salt or anything you like. Bake for 7-10 minutes until dark green and crispy, but be careful not to burn!
