Creating the Greek Chicken Pita Wrap is simple if you follow these easy steps:

1. Marinate the Chicken: In a bowl, whisk together olive oil, lemon juice, oregano, garlic, salt, and pepper. Add the chicken breasts and coat well. Let it marinate for at least 30 minutes in the refrigerator.
2. Cook the Chicken: Preheat a grill or skillet over medium-high heat. Remove the chicken from the marinade and cook for 6-7 minutes on each side, or until fully cooked and no longer pink in the center. Remove from heat and let it rest for a few minutes.
3. Slice the Chicken: Once the chicken has rested, slice it thinly into strips.
4. Prepare the Pita: Warm the pita bread in a skillet or microwave until soft and pliable.
5. Assemble the Wrap: Place a generous amount of chopped romaine lettuce in the center of each pita. Add slices of chicken, cherry tomatoes, cucumber, and red onion.
6. Add Tzatziki Sauce: Drizzle a good amount of tzatziki sauce over the top of the fillings.
7. Wrap It Up: Fold the pita over the fillings, pressing gently to secure everything inside.
8. Serve Immediately: Enjoy your delicious Greek Chicken Pita Wraps fresh!

These straightforward steps ensure that you can create this incredible wrap easily and enjoyably.
