Combine all the ingredients in a large bowl. Cover with plastic wrap and marinate in the refrigerator for at least 4 hours.

Place two skewers beside each other. Roll up each marinated chicken thigh and slide it onto both skewers.

Grill both sides of the skewered chicken thighs on high heat until fully cooked through (about 10 minutes per side).

Using a sharp knife, slice off a desired amount of chicken and place it into each pita. Top with your favorite toppings. I like to use Romain lettuce, cherry tomatoes, red onion, cucumber, and of course Greek yogurt sauce.
