Roll out the cooled dough as round as possible on a floured surface, place in a greased dish and pull up one edge. To avoid bubbles, poke holes in the bottom with a fork. Spread the cheese cream on the dough and top with the tomatoes, then sprinkle the remaining grated cheese over the top, pepper and drizzle with a little oil.
