Follow these simple steps to create the flavorful Greek Chicken Bowls with Creamy Tahini Feta Sauce:

1. Marinate the Chicken: In a large bowl, combine olive oil, oregano, garlic powder, salt, and pepper. Add chicken breasts and toss to coat well. Let marinate for at least 15 minutes.

2. Prepare Quinoa/Rice: While marinating, cook quinoa or rice according to package instructions and set aside.

3. Make the Sauce: In a separate bowl, whisk together tahini, olive oil, lemon juice, minced garlic, and water. Season with salt and pepper. Adjust the consistency with more water if needed.

4. Cook the Chicken: Preheat a grill or grill pan over medium-high heat. Cook chicken for about 6-7 minutes on each side until fully cooked and juices run clear.

5. Slice the Chicken: Once cooked, remove the chicken from the grill and let it rest for a few minutes before slicing it into strips.

6. Prepare the Bowls: In serving bowls, start by placing a scoop of quinoa or rice at the bottom.

7. Add Vegetables: Top each bowl with diced cucumber, cherry tomatoes, red onion, olives, and a handful of mixed greens.

8. Add Chicken: Arrange sliced chicken on top of the vegetables in each bowl.

9. Drizzle with Sauce: Generously drizzle the Creamy Tahini Feta Sauce over each bowl.

10. Garnish: Finish with crumbled feta cheese and fresh parsley for extra flavor and color.
