Preheat oven to 375 degrees F and line baking sheet with unbleached parchment paper.

Rinse cauliflower, remove the outer leaves, separate into florets and chop into smaller pieces. Process in a food processor in batches, until 'rice' texture forms.

Transfer riced cauliflower on a prepared sheet pan or any oven safe baking dish and bake for 15 minutes or microwave in a microwave-safe bowl for 8 minutes.

Transfer cooked cauliflower to a large bowl lined with double layered cheesecloth or linen towel, and let cool for 10-15 minutes or until safe to the touch.

Hold onto 4 corners, twist cauliflower into a ball and squeeze the liquid out as hard as you can until barely any liquid comes out.

In a large bowl, add dry cauliflower, egg, cheese, Italian seasoning, salt and pepper. Mix very well with spatula until combined.

Line same baking pan or pizza stone with new parchment paper and spray with cooking spray. Transfer cauliflower pizza dough in the middle and flatten with your hands until thin pizza crust of about 11 inches in diameter forms.

Bake crust for 20 minutes. If you would like more crispy crust, carefully flip it with spatula and bake for a few more minutes.

Top cauliflower pizza base with your favorite toppings and bake again until cheese on top turns golden brown.

Let cool 1-2 minutes, cut into 8 slices with a pizza cutter and enjoy!
