Cook the cauliflower rice according to instructions, allow to cool and squeeze out all remaining the liquid.
In a bowl combine cauliflower rice, cheese, beaten egg, garlic powder, all seasonings and mix well. Transfer your dough to a baking tray lined with parchment paper and press with your hands to form a circle.
Bake for about 10-15 minutes or until golden. Spread marinara sauce, add mozzarella on top and return back to the oven. Broil until cheese melts, approximately 3-5 min. Slice and serve.
