1. Preheat oven to 425 degrees Fahrenheit. Line a baking sheet with Gefen Parchment Paper.
2. Using a food processor or box grater, grate cauliflower. You should have two cups cauliflower crumbles. Place in a large bowl and microwave for four minutes to soften. Let cool. Place in a large kitchen towel and strain well.
3. In a bowl, combine egg, Parmesan, shredded mozzarella, basil, oregano, garlic powder, salt, and pepper. Add cauliflower and mix. Scoop out one-fourth cup of the mixture and shape into a mini pizza. Place on prepared baking sheet. Repeat with remaining cauliflower mixture. Bake for 10 to 15 minutes, until golden.
