Who needs grains when you have sweet potatoes. There's gluten free and then there's grain free. In this pizza you get both. The crust is thin and crispy and made with sweet potatoes (not a grain in sight). It's topped with four cheeses melted together in delicious harmony. Mmmm, am I right? Sweet potato crust. Mozzarella cheese. Fontina cheese. Proveolone cheese. Parmesan cheese.
