Wash and de-stem the greens and put in a mixing bowl. You can cut the leaves into smaller sizes to make eating easier (and cleaner).
In a food processor, blend the leeks/spring onions until very fine. Add to the mixing bowl with the greens.
Add the spices and coconut oil. Mix thoroughly with your hands until everything is covered.
In your dehydrator: Dry at 65C for about 5 hours until crisp.
In your oven: Dry at 80C for about 2 hours until crisp. Be sure to use the fan setting and put a fork or tablespoon in the oven door for the moisture to escape and prevent chips from going soggy.
