Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
Break the cauliflower into florets and pulse in a food processor until fine. Steam in a steamer basket and drain well. (I like to put it on a towel to get all the moisture out.) Let cool.
In a bowl, combine the cauliflower with the mozzarella, Parmesan, oregano, salt, garlic powder and eggs. Transfer to the center of the baking sheet and spread into a circle, resembling a pizza crust. Bake for 20 minutes.
Add desired toppings and bake an additional 10 minutes.
Note: you can use frozen cauliflower though it is tricky to get all the water out. It is possible to drain it well.
