Rice cauliflower using the food processor's shredder blade. Alternatively, you can grate the cauliflower with a cheese grater.

Place the riced cauliflower in a microwave safe bowl, add 1/4 cup water, and microwave for 6-8 minutes, stirring half-way through.

To make the pizza, preheat the oven to 450 degrees F. Generously grease a pizza pan or cookie sheet with olive oil or non-stick cooking spray.

In a medium bowl, combine the cauliflower, mozzarella cheese and egg together and stir until well incorporated. Add the oregano, garlic, and garlic salt. Transfer to the cookie sheet, and shape into a 9-inch circle. Brush the crust with olive oil to help it brown in the oven.

Baked at 450 degrees F for 15 minutes, until the crust is browned and cooked through the middle.

Remove the crust from the oven, add your sauce and toppings. Place under a broiler at high heat until the cheese is melted and bubbly. (About 3-4 minutes).

Allow the pizza to cool slightly, then cut into small slices and serve.
