Making your Mediterranean Chicken Flatbread is straightforward if you follow these simple steps:

1. Marinate the Chicken: In a bowl, combine olive oil, oregano, garlic powder, salt, and pepper. Add chicken breasts, ensuring they are well coated. Let it marinate for at least 30 minutes.

2. Preheat the Grill or Oven: Set your grill or oven to medium-high heat, around 400°F (200°C).

3. Cook the Chicken: Grill or bake the marinated chicken for about 15–20 minutes, or until the internal temperature reaches 165°F (75°C). Once done, remove from heat and let it rest for a few minutes.

4. Slice the Chicken: After resting, slice the chicken breast into thin strips.

5. Prepare the Flatbreads: While the chicken is resting, you can warm the flatbreads on the grill or in the oven for about 3–5 minutes.

6. Assemble the Flatbread: Lay the warm flatbreads on a serving platter. Spread a generous amount of tzatziki sauce on each flatbread.

7. Top with Chicken and Vegetables: Evenly distribute the sliced chicken over the flatbreads. Add cherry tomatoes, cucumber, red onion, and sprinkle crumbled feta cheese on top.

8. Garnish: Finish with a sprinkle of fresh parsley for added flavor and presentation.

9. Serve Immediately: Enjoy your Mediterranean Chicken Flatbread while warm!
