I start by patting the chicken dry and slicing it into thin strips. Then, I mix all the marinade ingredients in a bowl and coat the chicken evenly. Cover and chill for at least 30 minutes, though I prefer 4-24 hours for maximum flavor.
I heat my skillet over medium-high heat with a bit of olive oil. The chicken goes in a single layer, seared until golden brown and slightly crispy. After cooking, I let it rest for a few minutes under foil to retain juices.
I warm the pita bread in the oven or microwave until soft. Then, I slice the vegetables thinly and set everything out so assembly is easy. This step ensures the pita stays soft and the toppings fresh.
I spread a generous layer of sauce inside the warm pita, then add the cooked chicken. Next, I pile in cucumber, tomato, onion, and lettuce, finishing with parsley. Serve immediately for the best texture and flavor.
