Place the diced sweet potato or potato in a steaming basket set over boiling water. Steam for 15 to 20 minutes, until tender when pierced with a fork. Remove and set aside until cool.
When cool, place the steamed sweet potato or potato in a bowl and mash until smooth. Add the cassava flour, garlic powder and dried oregano. Knead with your hands until you get a soft, smooth dough, adding more flour as needed.
Preheat oven to 350°F/180°C. Line a large baking tray with parchment paper. Roll out the dough on a lightly floured surface or in between two sheets of parchment paper. If the dough breaks, press it together again. Place the pizza base on the baking tray and prick with a fork. Bake for 10 to 20 minutes, until firm and lightly browned on the edges.
While the pizza base cooks, combine all the salad dressing ingredients in a high-speed blender and blend until smooth.
When the pizza base is cooked, set it aside to cool for 5 minutes before adding the salad on top. Serve immediately. Enjoy!
