Preheat oven to 450 degrees farenheit.
In a medium bowl, combine cauliflower, egg and mozzarella. Press evenly on the pan. Sprinkle evenly with fennel, oregano and parsley.
Bake at 450 degrees for 12-15 minutes (15-20 minutes if you double the recipe. Make sure your cookie sheet is greased (: )
Remove the pan from the oven. To the crust, add sauce, then toppings and cheese.
Place under a broiler at high heat just until cheese is melted.
