I know, it is a pretty long list of spices. The good news is that if you're missing one or two, it's really not a deal breaker. Just go ahead and use what you do have. If you have any questions about substitutions, please ask in the comments below. Or, if you can find a pre-made shawarma spice blend at your store, that will work, too! McCormick makes a shawarma seasoning, and Penzey's sells a Turkish seasoning blend that will work well for this chicken shawarma recipe.
