Preheat your oven to 450°F (230°C).
Rice the cauliflower using a food processor.
Steam the riced cauliflower for about 5 minutes until tender.
Let it cool, then wring out excess moisture using a cheesecloth.
In a bowl, combine the cauliflower, mozzarella, Parmesan, egg, garlic powder, oregano, salt, and pepper.
Spread the mixture onto a parchment-lined baking sheet, forming a crust.
Bake for 12-15 minutes until golden and crispy.
Remove from the oven and let it cool slightly.
Add your favorite toppings.
Return to the oven for an additional 10 minutes until the cheese is bubbly.
