Transfer the dough to the work surface and roll it out to fit your baking tray. Make sure the dough is rolled thinly. Place it on the tray and leaving ½" from the pastry edge, spread the tinned tomatoes as your base, add some chopped fresh tomatoes. Layer your toppings on top and finish with a layer of cheese.
Transfer to the oven and bake for a further 15-20 minutes until the cheese is bubbling and everything is well cooked through.
