Yes it’s really cauliflower, and a much healthier alternative than regular pizza crust. Nobody will know it's cauliflower though! It is seriously that good!
Wash the head of cauliflower and pat it dry removing as much moisture as possible. Chop into bite size pieces and toss them into a food processor and process until it is the size of rice.
Put the riced cauliflower into a microwave safe bowl and microwave for 7-8 minutes until it has softened and appears cooked.
Preheat your oven to 450 degrees F
Spray a pizza pan with plenty of non-stick cooking spray. You can also use parchment paper if you have it. Spray the parchment paper with a light coat of cooking oil.
In a medium bowl, combine the cauliflower, egg whites, mozzarella, oregano and garlic.
Press evenly in the pan. Push it down into all the corners making sure its stuck to itself pretty well. Sprinkle with parmesan cheese.
Bake at 450 degrees for 12-15 minutes.
Remove the pan from the oven. Add your sauce, toppings and cheese.
Place under a broiler for about 30-60 seconds, just until the cheese is melted. Watch it carefully or it will burn.
