Toss together the slaw ingredients. Put the chicken breasts between pieces of clingfilm and beat with a rolling pin to about 1cm (½in) thick.
Mix together the Parmesan, breadcrumbs and parsley on a plate. Season the flour and put on another plate. Put the egg on a third plate. Dip the chicken first in the flour, then in the egg and then in the breadcrumbs.
Heat the oil in a large frying pan and cook the chicken for about 3-4 minutes on each side. Cut into a thick portion to ensure that it is cooked through, with no pink showing. Serve with the slaw and boiled new potatoes, if you like.
