Italian fried cheese sandwich (mozzarella in carrozza) with prosciutto and grilled vegetables

Warm vegetable oil in a saucepan, as much as liked.

Mix one egg per sandwich with 100 ml milk, salt and pepper very well; set aside. Set out a little flour.

Cut the crusts off a moist bread. Layer sliced fresh mozzarella, thin slices of prosciutto, grilled sweet potato, grilled zucchini and asiago, then close the sandwich.

Press hard; dip every edge in the flour, then into the eggs, covering the edges and sides, so the oil does not get inside and make it heavy.

Fry in oil at 150 degrees for about two minutes, until golden brown and the mozzarella has melted inside.
