Remove the pan again; the dough will have puffed up a bit. Use a brush to brush the tomato sauce over the surface, deflating the dough somewhat, but leave a ½-inch border around the edges. Brush the border with the olive oil. Distribute the havarti
evenly over the tomato sauce covered portion and add any additional toppings you would like. Sprinkle over the oregano and the red pepper flakes, if using.
