Heat the tigelle/muffin on a griddle or in the oven for a few minutes, until they are slightly crispy on the outside but still soft on the inside. Meanwhile, wash and dry the salad. Dress to taste with a drizzle of extra virgin olive oil, salt and a grinding of black pepper.
Cut the tigelle/muffin in half and fill them with a bed of fresh salad, add a few shavings of Grana Padano PDO and a couple of slices of prosciutto crudo per tigella, close and serve.
