Preheat oven to 425 degrees.
In a large bowl combine arrowroot starch, coconut flour, baking soda, salt, herbs and garlic powder. Toss to combine.
Add in olive oil and stir to incorporate it.
Slowly add in warm water to the starch/flour mixture, mixing well after each addition.
Mixture will be slightly crumbly but should hold its’ form if pressed together.
Divide dough in half and form each half into a ball. Place each ball of dough on its’ own piece of parchment paper.
Using a rolling pin, slowly roll each ball of dough into equal-sized circles that are ¼-inch thick. You may need to press the edges of the dough together as you go along since they will have a tendency to crack.
Place each piece of parchment paper (with pizza dough circles) onto a baking sheet or pizza stone. Bake for 11 minutes.
Remove pizza crusts from the oven and top with equal amounts of goat cheese, caramelized onions, and roasted beets.
Return pizzas to the oven and continue cooking for an additional 3-5 minutes.
Top pizzas with toasted pine nuts and arugula. Serve immediately and enjoy!
