Preheat oven to 350 F. Wash and grate zucchini. Squeeze the water out of the zucchini and place in a medium bowl, discarding the zucchini juice. Add in the arrowroot flour, coconut flour, eggs and spices. Mix until well combined. Line a 9 x 11 baking sheet with parchment paper. Using a 6cm ice cream scoop, scoop the tortilla batter on to the baking sheet, using your fingers to press the batter until thin round-shaped tortillas. Bake for 40 minutes or until tortilla is golden brown. Serve with your favorite taco toppings!
