It's a popular gourmet sandwich that can probably be never made at home perfectly, but wait, there's a very easy way out. I did mine using a panini grill at home. Marinated chicken chunks are mounted on a large rotating skewer and then roasted slowly to perfection against a gas burning grill. Due to unavailability of such industrial roasters at homes, this has typically remained a restaurant dish. I am sure you all will love it. The basic concept in this recipe is to have a nice marination that mimics a good chicken shawarma flavour and then grill it in such a way that keeps it juicy. Happy cooking!!!!!!!.
