If using the chicken, butterfly each breast and place between wax paper. For pork, place chops several inches apart between wax paper. For veal, if you have large, thin-cut pieces, use as is. If the veal is more than 1/4 inch thick, place between wax paper. Pound the meat until very thin.
Season the meat with salt and pepper and dust in the flour.
Beat the eggs and milk or cream in a large shallow dish.
Combine the bread crumbs with the nutmeg and more salt and pepper and place on a large plate.
Coat the meat in egg, then in crumbs.
Heat a large non-stick skillet over medium to med-high heat with just enough oil in it to thinly coat the bottom of the pan. When the oil gets wavy looking, add the meat in a single layer and cook until golden on each side, about 3 minutes each. Transfer meat to a plate and repeat, if necessary.
