Baharat Shawarma Seasoning

Traditional Turkish shawarma is a well-marinated meat, layered on a vertical rotisserie or spit where it's slow roasted for days in its own juices and fat, until perfectly tender and extra flavourful!  To serve it, typically they shave a layer of shawarma off the spit and pile it up into a pita pocket, jazz it with tahini sauce and heaps upon heaps of fresh toppings!
