Thanks Lyn (see profile) for finding this recipe on http://www.fitsugar.com/Low-Carb-Cauliflower-Crust-Pizza-Recipe-30739512

INGREDIENTS:

Nonstick spray
2 1/2 cups grated cauliflower (about 1/2 a large head)
1 large egg, lightly beaten
1 1/4 cups shredded part-skim mozzarella cheese
2 tablespoons grated parmesan cheese
salt and freshly ground black pepper
1/4 cup tomato sauce
1 cup cherry tomatoes, sliced in half
2 cloves garlic, sliced
1/4 teaspoon crushed red chilli flakes
Fresh basil leaves, optional

DIRECTIONS

    Line a rimmed baking sheet with parchment paper, and preheat oven to 425ºF.
    Grate the cauliflower using a box grater until you have two cups of cauliflower crumbles. Place in a large bowl and microwave for seven to eight minutes, or until soft. Remove from the microwave and let cool.
    Mix in the egg, one cup mozzarella, parmesan cheese, and salt and pepper. Once combined, pat into a 10-inch round on the prepared pizza pan. Spray lightly with nonstick spray and bake for 10 to 15 minutes, or until golden.
    Top the pizza with the sauce, 1/4 cup mozzarella, cherry tomatoes, garlic, and red chilli flakes. Bake in the oven until melted and bubbly, another 10 minutes. Top with basil before serving.
