Grate the cauliflower into small crumbles. Place the cauliflower crumbles into a large bowl and microwave for 8 minutes. Set aside to cool completely.
Preheat the oven to 450 degrees. Spray a cookie sheet or pizza pan with nonstick spray or line with parchment paper.
When the cauliflower has cooled, add the remaining crust ingredients to the bowl, stir to combine. Pat the mixture into a 10 to 12-inch round on the prepared pan. Bake for 15 minutes (or until golden). Remove the crust from the oven, and turn the heat up to BROIL.
Spread the sauce on top of the baked crust, leaving a 1/2-inch border around the edge. Add toppings and sprinkle with cheese.
Broil the pizza 3 to 4 minutes, or until the toppings are hot and the cheese is melted and bubbly. Cut into 6 slices and serve immediately.
