Creating a Greek Chicken Gyro Bowl is straightforward and fun when you follow these simple steps:

1. Marinate the Chicken: In a bowl, whisk together olive oil, Greek yogurt, lemon juice, minced garlic, oregano, salt, and pepper. Add the chicken breasts and coat them well. Allow to marinate for at least 15 minutes (you can also do this overnight).

2. Preheat the Grill/Pan: If using a grill, preheat it to medium-high heat. If using a stovetop, heat a non-stick skillet over medium-high.

3. Cook the Chicken: Grill or cook the marinated chicken for 6-7 minutes on each side or until fully cooked and the internal temperature reaches 165°F (75°C). Remove from heat and allow to rest.

4. Prepare the Vegetables: While the chicken cooks, prepare your fresh vegetables by washing and slicing them as needed.

5. Slice the Chicken: Once rested, slice the chicken into thin strips.

6. Assemble the Bowl: In bowls, start with a base of mixed greens. Add sliced chicken on top, followed by cherry tomatoes, cucumber, red onion, and crumbled feta cheese.

7. Add Tzatziki: Drizzle tzatziki sauce over the assembled bowl as a finishing touch.

8. Serve: Enjoy your Greek Chicken Gyro Bowl as is, or add pita bread or pita chips on the side for a crunchy contrast.
