How to make
Clean the meat of excess fat. Cut it butterfly style, so as to be able to dissolve, to be filled and subsequently roll them up. Sprinkle with plenty of salt and pepper.
Mix and beat well all the products for the marinade. Pour over the meat and let it marinate for a few hours in the cold and turn it occasionally. Then fill with thinly sliced onions, carrots, pickles, optional olives and nuts and turn a tight roll. If it does not hold, pin it up with chopsticks.
Put it in a well greased tray. Pour a trickle of oil and pour most of the remaining marinade in the tray. Cover with foil and put to bake for an hour and a half. Then remove the foil, brush the roll with marinade and bake until it gets a nice tan.
