I found this recipe on a website that appeared to represent an ongoing Donair,(as we call them in Canada) business. Lamb and mutton are not very popular in this country. Statistically, chicken, beef and pork are way out front, in that order. We eat many European and even Down Under dishes but modify the sheep component to one of the above.
Everything in excess! To enjoy the flavor of life, take big bites. Moderation is for monks.
