Ingredients:
1 pound of raw kale, stripped and shredded into four inch pieces
Juice of two limes
3/4 cup of nutritional yeast-mixed with garlic powder

Preparation:

Preheat your oven to 220 degrees Fahrenheit.

Make sure you strip the kale, because if not, the stems will take longer to dehydrate.

Put kale in a bowl, and pour lime juice over the greens. Mix with your hands, so that all of the leaves are moistened with juice.

Very generously, sprinkle the nutritional yeast on all of the leaves, and mix with your fingers, so that all of the kale is coated.

Get a big cookie sheet, line it with parchment paper. Place the greens on the sheet, and arrange them so that they do not cover one another.

Place on the middle rack of your oven, close the door, and allow them to bake for about 30 minutes.

How do you tell they are done? Well, they will turn a very, very dark green in color. Some of the leaves might take flight in the oven. They are crispy, light and dry. Varies with your oven.

You won’t have to worry about storage of these, because everyone will scarf these things up in a few minutes. Great as a side dish with a veggie burger, or even perfect to serve to friends when they come over.
