Preheat the oven to 375°F and line your baking tray with parchment paper.
In a small mixing bowl, combine wet ingredients: apple cider vinegar, olive oil, and water. Whisk together and set aside.
In a medium-sized mixing bowl, combine dry ingredients: almond flour, arrowroot starch, potato starch, garlic powder, baking soda, salt, and flaxseed meal. Carefully mix them until well combined.
Now, mix the wet ingredients into the dry ingredients. Mix it well until it starts to form a dough then start kneading. Add more flour if the dough is too wet or sticky. On the other hand, add a little more water if it's too dry.
Shape the dough into a circle or square, whichever you prefer. Use a rolling pin to flatten and shape it. You may also make it as thick as you want but a quarter-inch thick is ideal.
Transfer the dough into the prepared oven tray and bake for 10 minutes. Meanwhile, start preparing your toppings.
Remove the pre-baked dough in the oven and crank up the oven temperature to 475ºF.
Pour the pizza sauce onto the dough and spread evenly, leaving the edge a quarter to half-inch empty.
Arrange all the toppings over and bake for another 10-15 minutes, or until the toppings are toasted and the crust is firm and slightly golden brown.
Remove from the oven, sprinkle with parmesan cheese, and garnish with fresh parsley, oregano, or basil. Divide into 6 slices. Serve and enjoy!
