In a bowl; add all ingredients for the Chicken and mix well. Optionally; marinate it for 30mins or overnight(turns out softer and more flavorful). Spread it on a baking tray and bake for 20 mins; flipping halfway through.
For yogurt sauce; mix all the ingredients together and it's ready.
I mix all toppings together except the lettuce.
Heat pitas with a bit of oil. Cut them in half and let the steam out.
SERVING:
Layer pita with lettuce, and chicken along with the cucumber mix. Top with yogurt sauce. Enjoy!
