The total quantity of the three ingredients is as much as the chicken can accommodate and the proportion is in equal parts. Mix the olives, the yellow cheese and the walnuts – cut the yellow cheese in cubes before that. Add black pepper at will. Clean the chicken well and fill it with the stuffing, then sew it up. Grease lavishly with oil and season with salt and black pepper. Place it in a baking tray and add water, then cover with foil. Bake in a moderately hot oven. Uncover the chicken a short while before taking it out of the oven in order to get crispy.
