Indian Chicken Kebabs

We used to live in the Middle East and we had some pretty fantastic food there.  There were lots of Indian people there, and they brought their food with them!  We loved getting kebabs there, and these were so good it was like being back in Asia.  Serve this with saffron rice and raita, and some warm pita or naan if you can find it!
