Pro Tip: To make the chicken more blackened and crispy, flash pan-fry it. Heat some neutral oil in a hot pan until it smokes. Then, add the chicken and leave it for a minute to create some texture. This will give the pita an authentic street-food vibe. However, you can also use cold chicken and enjoy it.
To heat the pita bread, you can either bake it in the oven briefly or toast it in a skillet.
