UK favourite Pizza Express posted instructions online to make several of its recipes, including that enduring classic, Margherita pizza. It doesn’t require anything out of the ordinary: just plain flour, water, sugar, yeast and olive oil to make the dough. The topping is passata, mozzarella, oregano and basil, and the entire dish can be ready within an hour. We'll leave it up to you if you want to go half-pizza, half-salad – or devour a whole one by yourself.
