Prepare the Marinade: In a medium bowl, whisk together ¼ cup olive oil, 2 tablespoons lemon juice, 1 teaspoon garlic powder, 1 teaspoon dried oregano, and salt and pepper to taste. This zesty marinade will infuse your chicken with Mediterranean flavors. Once well combined, set aside to allow the ingredients to meld while you prepare the chicken.

Marinate the Chicken: Using a meat mallet, pound 1 pound of chicken breasts to an even thickness of ½ inch. Place the chicken in the marinade, ensuring each piece is coated. Cover and marinate in the refrigerator for at least 30 minutes.

Make the Tzatziki Sauce: In a mixing bowl, combine 1 cup Greek yogurt, ½ cup diced cucumber, 1 minced garlic clove, 1 tablespoon lemon juice, and a pinch of salt. Stir until smooth and well blended. Chill in the refrigerator until ready to serve.

Cook the Rice or Quinoa: While your chicken marinates, prepare the base. Cook 1 cup of rice or quinoa according to the package instructions. Fluff with a fork and set aside to cool slightly.

Cook the Chicken: Preheat your air fryer to 380°F. Place the marinated chicken in the basket and cook for 7 minutes on one side. Flip the chicken and continue cooking for another 3-4 minutes until it reaches an internal temperature of 165°F.

Let the Chicken Rest: Once cooked, remove the chicken from the air fryer and allow it to rest for 5 minutes. After resting, slice the chicken into strips.

Assemble the Greek Chicken Bowls: Start by placing a scoop of rice or quinoa in each bowl. Top with sliced chicken, followed by a colorful assortment of fresh vegetables. Add a dollop of tzatziki sauce.

Serve and Enjoy: Garnish your Greek Chicken Bowls with any additional toppings you love, like feta cheese or olives.
