Tear the rolls into pieces, pour the milk over, let soften, squeeze out, and push through a sieve or mash smooth with a fork.
Soften the butter to room temperature, mix in the soaked bread, the breadcrumbs and the flour, working it together thoroughly.
Add the egg yolks and whole eggs, season with salt and pepper, and mix in the parsley - the filling should be a thick, creamy mass.
Cut a pocket into the veal breast or shoulder with a sharp knife from the side.
Fill with the stuffing, and sew the opening closed with kitchen string or strong thread.
Place in a greased roasting pan, preheat the oven to 170-180°C, and roast slowly for about 1 hr 15 min to 1 hr 30 min, basting with its own juices every 15-20 minutes.
The meat is done when a meat thermometer reads 70-72°C at the thickest part, and the surface is an even, lovely reddish-brown.
Rest for 10 minutes, remove the string, slice, and serve with the pan juices.
