Pre-heat oven to 425°F. Line a rimmed baking sheet with parchment paper.

Use food processor to pulse cauliflower into powder (you should have about 2 1/2 cups). Transfer cauliflower to a microwave-safe bowl and cover. Microwave 3 to 5 minutes until soft. Transfer onto a clean, dry kitchen towel for cooling.

Once cooled, wrap the cauliflower in towel and wring out moisture. In a large bowl, stir together the Cauliflower, Italian Seasoning, Parmesan Cheese, Salt, Egg and 1 Cup of Mozzarella Cheese until well combined. Transfer to the prepped baking sheet and press into a 10-in. round. Bake until golden brown, approx. 10 to 15 minutes.

Remove the crust from the oven and top with Sauce (see recipe below) and remaining 1 cup mozzarella and top with tomato slices. Bake until the cheese is bubbling, roughly 10 minutes. Chop basil leaves and top before serving before serving.
