Mix salt and flour in a wide flat bowl. Dip veal cutlets into the mixture to coat. Sauté in butter until lightly browned. Add the wine and simmer 2 to 3 minutes. Add the broth and stir until thickened.
Cover each cutlet with 1 slice of cheese and prosciutto. Sprinkle with poultry seasoning. Place on a pan and heat under the broiler until the cheese melts.
Baste the veal with the sauce from the pan and return to the broiler for about one more minute.
Sprinkle with parsley (or sage), and serve immediately.
