The Supreme Pizza

Preheat the oven to 475°. On a lightly floured work surface, using a lightly floured rolling pin, roll out each ball of dough to a 10-inch round. Transfer each round to a separate baking sheet. Brush the dough with olive oil, then spread the crushed tomatoes on top, leaving a 1/2-inch border. Top with the mustard greens, provolone, mortadella, onion and mozzarella. Bake on the middle and bottom racks of the oven for about 15 minutes, shifting the sheets halfway through baking, until golden brown and cooked through.

In a small bowl, stir the crushed red pepper with the 1/4 cup of olive oil. Drizzle the pizzas with some of the red pepper oil and garnish with Grana Padano. Pass the remaining red pepper oil at the table.
