This Xinjiang (western China) specialty can be found practically all over China.  It’s a mutton-kabob seasoned with cumin and ground red pepper.  Rumor has it that if you find a real Uygur making them they taste a lot better.  They cost from .50-1.00 rmb per skewer.  Although the barbecued style is the original (and arguably the best), a deep fried version using beef  or   or chicken is also popular in large shopping areas.
