Preheat the oven to 400°F (204°C).
Begin making sweet potato puree by taking 2 medium orange-fleshed sweet potatos (also called a yam) rinse and scrub them to get any remaining dirt off. Using a fork, stab holes around the surface of the sweet potatoes. Place them in a microwave safe bowl and microwave on high for 5-7mins, until very soft. To keep them from drying out, place a wet paper towel on top while microwaving for moisture. Once soft, remove from the microwave and peel off the skin of both potatoes; then mash in a bowl using two (2) forks until it has the consistency of applesauce. Set aside to cool. *Add optional seasonings at this step if desired (garlic, dried oregano, etc.*
Once sweet potato puree is cool enough to work with, place in a mixing bowl and begin gradually adding 1-2cups of Gluten Free All Purpose flour. Only add 1 cup of flour at a time; continue adding until the ball of dough begins to form.
Roll out dough thinly into the shape desired. Pinch edges to make a small crust.
Place dough on a baking pan (or pizza stone) and bake at 400°F (204°C) for 10mins, or lightly toasted.
Once lightly toasted, remove from the oven and top with your favorite pizza sauce and toppings. Place back in the oven to continue cooking for about 20mins, until cheese is melted and toppings are toasty.
