Place a baking sheet into your oven, turn to 450°

Rice a small head, or 1/2 large head, of cauliflower by pulsing about 15 times in a food processor until the size of grains of rice

Microwave the rice on high until tender (timing depends on your microwave)

Allow cauliflower to cool a bit and then dump into a thin tea towel. Carefully (you don't want to burn your hands!) squeeze out as much moisture as you can over the sink or a bowl.

Add herbs, salt, garlic powder, and cheeses to cauliflower and mix, allowing mixture to cool a bit more

Add egg and mix to incorporate well

Dump out onto a piece of parchment paper and press firmly into a circle of about 8-10" in diameter

Carefully slide the parchment paper and crust onto the hot baking sheet and place into the oven

Bake for 15 - 20 minutes until lightly browned

Top with your favourite pizza toppings and extra cheese

Bake an additional 10-15 minutes until toppings are done and cheese is melted
