This tomato pie is inpired by bakery cold pizzas that truly highlight tomatoes. For a strong tomato flavour, cover the crust with a spread made from roasted shallots, tomato paste, red wine and garlic for a true concentration of flavour. For the crust, make a simple shortcrust pastry in the food processor with plenty of Parmesan cheese. For the topping, use heirloom tomatoes (which have less water and are more flavourful), and bake to perfection. Be sure to salt the tomatoes beforehand to keep the water from soaking through the dough.
