Traditionally, Beef Shawarma is prepared by stuffing chunks of meat on a large skewer. It is then cooked slowly against a vertical gas roaster that rotates continuously. A chef slices the cooked meat into thin strips as it takes very long to cook the meat completely. Or, the meat chunks are put on top of the skewer so that they drip and flavor the meat as it cooks. The most common meat utilized for preparing shawarma are chicken, lamb, beef and even turkey. The shawarma that you get in restaurants is not the healthiest dish but it's worth having once in a while.
