Preheat oven to 350° F and grease a baking sheet with a bit of coconut oil.

In a mixing bowl, combine the coconut flour, arrowroot, cassava flour, herbs, salt, and baking soda.

Mix in the egg whites and coconut oil.

Form the dough into a ball and press and pat it out on the baking sheet as thin as possible.

Bake for about 5 minutes.

Use a pizza cutter to cut into squares and bake for 25-20 more minutes, turning a couple times, or until golden browned and crisp.
