Buy a leg of a lamb. Let your butcher take off the excess fat and skin. Cook it in a saucepan with small onions, 1 teaspoon salt and enough water to cover. Remove froth from top and cook until tender. Remove from saucepan and place on an oven pan.

Mix yoghurt, tomato paste and 1 tablespoon of melted margarine. Spread this sauce on the meat. Roast in medium hot oven until crisp and serve with potatoes and peas. You may add another sauce, too.
