Taken from the Polpo cookbook, pizzettas are simple and quick to make. This recipe redefines pizza as there is no tomato or garlic and they are unbelievably delicious.
1 ball of pre-made dough (see pizzetta dough recipe)
1 small handful of cheap grated block mozzarella
1 small handful of finely grated Parmesan
Quarter of a small red onion, very thinly sliced
A sprinkling of fresh thyme leaves (not the stalk)
