You can add what ever topping you want I think I put sausage mushroom black olives and pepperoni and yes parmesan. The crust it what screws with diabetics. This crust is made from mostly cheeses. 2 cups mozzarella 2 ounces cream cheese and 1 egg and about 3 tablespoons of coconut flour. If my memory serves me. You melt the cheeses in microwave 30 seconds at a time until it makes a smooth melty goo. Let cool slightly add the coconut flour and egg mix until well combined. It will form a ball like a real dough. Roll it out between 2 parchment papers. Cook like 6 minutes flip cook another few minutes until it starts to brown then take it out snd top it cook until it is the way you like it. The BEST low carb recipe I have ever come across. I have many.That looks pretty good, Jan. Has it got parmesan cheese on it?
