Finely dice the veal, crumble the sausage, and sauté them in the butter. When they have browned, sprinkle the wine over them, let it evaporate, stir in the diced lard, and continue sautéing gently for 5-10 minutes (you want the meat to brown but not burn). Stir in the broth and simmer for five minutes, then remove the meats to a bowl with a slotted spoon, leaving the drippings in the pot.
Stir two heaping tablespoons of the bread crumbs into the drippings. Grind the meat mixture and combine it with the breadcrumbs you stirred into the drippings, then lightly beat one of the eggs and work it into the filling too, with the parsley, grated cheese, and nutmeg. Check seasoning and let the filling rest for a half hour.
Pit the olives if they weren't already pitted, and fill them. The easiest way to do this is to put the filling in a pastry bag or syringe of the kind used for frosting, with a fairly fine nozzle, and squirt the filling into the holes.
Lightly beat the remaining egg. Roll the filled olives in flour, then in the egg, and then in the bread crumbs.
Fry them in abundant oil for 15-20 minutes, drain them well, and serve them.
