Grate cauliflower into rice consistency using either your food processor or a box grater.
Preheat oven to 350 degrees F. Spread cauliflower onto a parchment-lined baking sheet into as flat of a layer as possible. Bake for 20 minutes, or until the cauliflower begins to brown. Remove from oven and let cool slightly. Increase oven temperature to 450 degrees F.
Spoon cauliflower into a cheesecloth and squeeze out as much moisture as possible.
In a large bowl, stir to combine cauliflower and all remaining ingredients.
Shape dough into a pizza round on a parchment-lined baking sheet. Bake for 15 minutes, carefully flipping the pizza crust halfway through cooking*.
Top pizza crust with your favorite sauces and toppings, then return to the oven until all melty and delicious, about 7 minutes.
*A trick to make flipping the crust easier: Set another parchment paper on top of the dough, and a large plate on top of that (if this were a sandwich, the baking sheet and plate would be the bread, and the pizza crust would be the filling!). Flip the “sandwich” all at once then simply slide the pizza crust onto the baking sheet.
