Rice balls make a marvellous quick lunch or can be served as part of an antipasti platter.
Roll leftover rice into balls. Make a hollow in the centre of each ball and fill with cubes of mozzarella (and ham if desired). Roll the ball so that the filling is enclosed, then coat with seasoned flour. Dip in beaten egg and then roll in fresh breadcrumbs mixed with freshly grated Parmesan. Refrigerate for about 30 minutes. Fry until golden, drain and serve.
