Preheat oven to 450 degrees. Line a baking sheet or pizza stone with greased parchment or a Silpat.
Place the cauliflower in a microwave-safe bowl and cover. Microwave on high for 4 minutes. Line a colander with cheesecloth or a dish towel and pour the hot cauliflower on top. Once the the cauliflower has cooled and started to drain, wrap it up in the towel and squeeze out as much moisture as possible. This is a critical step, don’t skip it.
Add cauliflower and all other ingredients to a large bowl, and mix until thoroughly combined. Turn the dough onto the parchment or Silpat, and spread into desired shape, leaving the crust about ¼ inch thick. Bake for 12-15 minutes, or until edges are beginning to look crispy and brown. Remove from oven and add sauce and desired toppings, bake for 5-8 minutes more.
