http://en.wikipedia.org/wiki/Shawarma

Shawarma is made by placing strips of meat or marinated chicken on a skewer. Animal fat and an onion or tomato is placed at the top of the stack to provide flavoring. The meat is then roasted slowly on all sides as the skewer rotates in front of or over a flame for a period of several hours (see rotisserie). Traditionally a wood fire is used, but nowadays a gas flame is more common.

The cooked meat is then shaved off the skewer with a large knife, dropping to a circular tray below to be retrieved. Shawarma is most commonly eaten as a fast food, made up into a sandwich with pita bread or rolled up in Arabic lafa (a sweet, fluffy flatbread) together with vegetables and a dressing. Vegetables commonly found in shawarma include cucumber, onion, tomato, lettuce, parsley, pickled turnips, pickled gherkins and cabbage.

http://en.wikipedia.org/wiki/Donair

The meat used for making döner kebabs may be lamb, beef or chicken, but never pork. After the BSE crisis (mad cow disease), even fish was used. Generally a döner kebab sandwich is served with a salad made from shredded lettuce. Usually there is a choice between a hot sauce, a yoghurt sauce containing garlic and a yoghurt sauce containing herbs. Sometimes sheep's cheese (Turkish: beyaz peynir, or "white cheese") can be added.
There are two basic ways of preparing meat for döner kebabs:

• The most common and authentic method is to stack seasoned slices of lean meat onto a vertical skewer in the shape of a cylinder. The stack is cooked by radiant heat from electric elements or gas fired infrared burners. Often fatty meat, tomatoes, and onions are placed at the top of the stack to drip juices over the meat keeping it moist.
• Some cheaper shops serve a combination of seasoned sliced and ground meat cooked on a grilltop as döner kebab. In Germany the amount of ground meat is not allowed to surpass 60% (Berliner Verkehrsauffassung).

A variation on the döner kebab known as a Donair was introduced in Halifax, Nova Scotia, Canada in the early 1970s. A restaurant called King of Donair claims to have been the first to serve this version in 1973.
The meat in this version of the döner kebab (Halifax donair, as it is sometimes referred to) is sliced from a loaf cooked on a vertical spit, made from a combination of ground beef, flour or bread crumbs, and various spices, while the sauce is made from evaporated milk, sugar, vinegar, and sometimes garlic. The meat and sauce are served rolled in pita bread with diced tomato and onion. This version is generally so packed with ingredients, that the pita is almost there for ceremonial purposes; the pita of any true Haligonian donair will be so soaked in sauce that attempts to pick it up will be fruitless.
This version of the donair is very popular across Canada, with many fast food pizza restaurants also featuring donairs on the menu.

A very similar variation of the Donair has popped up in Ontario and is called the Shawarma
