Using a small amount of flour, dust your Ooni pizza peel. Stretch the pizza dough ball out to 12”/16” and lay it out on your pizza peel. Drizzle a little olive oil over the pizza base – spread the oil using a pastry brush, the back of a spoon or your fingers to create an even, light layer of oil. Top with half of the Gruyère cheese and half of the cream, then sprinkle over the cooked bacon, cooked leek and the rest of the cheese.
