Add the chicken to the mixture and let it                                marinate for 30 minutes to 3 hours                                (refrigerated).
 2.To make the Tzatziki                                Sauce: Place the grated cucumber on a paper                                towel and twist to squeeze the out the liquid.                                Combine the cucumber, Greek yogurt, lemon juice,                                olive oil, chopped dill and parsley in a bowl.                                Season with salt and freshly ground black pepper                                and chill until you are ready to serve.
                                3.Preheat the oven to 350F. Heat an oven-safe                                sauté pan over medium-high heat. Sear the chicken                                to brown it on both sides and then transfer the                                pan to the oven for 8 to 10 minutes to cook                                through. (Alternately, you could air-fry the                                chicken at 380°F for 12 minutes, flipping it over                                halfway through the cooking process.) Let the                                chicken rest on cutting board for a few minutes                                and then slice it lengthwise into strips.
                                4.Heat olive oil in large sauté pan. Place each                                pocketless pita bread in the pan and heat for 2                                minutes on each side to warm and crisp the                                bread.
 5.Place the pita on piece of                                parchment paper slightly wider than the bread.                                Spread some Tzatziki sauce on the pita bread and                                top with some green leaf lettuce. Place chicken                                breast strips over the lettuce and sprinkle diced                                cucumbers, tomatoes, and red onion on top. Dollop                                some more tzatziki sauce and fold the pita bread                                up wrapping the parchment paper around the gyro to                                keep it shut. If desired, wrap some foil around                                the parchment paper to keep the gyro warm and                                serve it up food truck style!
