Preheat oven to 450 F. Grease a piece of unbleached parchment paper with oil.

Using a food processor or a box grater, grate the cauliflower very fine. It should be like snow. You should have 3 cups.

Place cauliflower snow in a glass bowl and microwave for 4 minutes. Let cool slightly.

Using a tea towel, place the cauliflower on the tea towel and ring out the water. Make sure you do this step or your crust will not hold together.

Place rung-out cauliflower, egg, coconut flour, oregano, sea salt and garlic powder in a large bowl. Mix well with your hands to combine.

Place the cauliflower mixture on the greased parchment and pat out to make a dense round.

Transfer to the oven and bake 12-15 minutes to golden.

Remove from oven and add your toppings. Spread on the marinara, add the mozzarella, then layer on the tomatoes.

Return to the oven for 2-5 minutes to melt the cheese.

Sprinkle with basil, drizzle with olive oil and serve.
