Preheat oven to 450 degrees. Link baking sheet with parchment paper and spray with cooking spray.

For the cauliflower: Cut the florets into chunks and pulse in a food processor until they look like rice. if you don't have a food processor you can use a cheese grater.

Microwave the riced cauliflower for around 5 minutes. Do not add water.

In a medium bowl, combine cauliflower, 1/2 cup mozzarella cheese, Parmesan cheese and egg.

Add Italian seasoning and garlic and mix until well combined.

Place dough on the baking sheet and press out to about a 9 inch round.

Bake 15-18 minutes. the edges will look burnt, but it really doesn't taste like it at all.

Remove from oven and add your pizza sauce, toppings and final 1/2 cup mozzarella cheese.

Place pizza back in the oven under the broiler, just until the cheese melts, usually around 3-5 minutes.

Serve immediately and refrigerate leftovers for up to two days.
