For the 1 cup of sweet potato, I just placed a large sized potato in the microwave for 8 mins until soft. Allow to cool and then scoop out of skin and mash, measure 1 cup worth.

Add this to a bowl with the coconut flour, tapioca starch and seasonings. Then gradually add the water 1 tbs at a time and mix, each time check the mixture, keep adding the water, until it is dough like, you don't want it too dry, but you also don't want it too wet.You may need a little more water than I specified check after each tablespoon (different brands of coconut flour can vary)

Preheat oven to 180c fan, 200c or 400f (gas mark 6)

Line a round pizza tray with parchment paper, place the sweet potato dough onto the paper and flatten down into a round crust, not too thick, but not too thin. Spray over the top with oil

Place in the oven and bake for approx 30 min, dough should firm and just starting to go golden.

While pizza crust is baking you can make the toppings.

Mix the pizza sauce ingredients together in bowl.
