Creating Greek Chicken Bowls is simple and rewarding. Follow these steps to prepare your delicious meal:

1. Marinate the Chicken: In a bowl, mix olive oil, garlic powder, onion powder, oregano, paprika, salt, and pepper. Add the chicken breasts and coat them well. Let it marinate for at least 15 minutes.
2. Cook the Chicken: Heat a grill pan or skillet over medium-high heat. Cook the marinated chicken for about 6-7 minutes on each side or until fully cooked. Ensure the internal temperature reaches 165°F (75°C). Remove from heat and let it rest for a few minutes.
3. Prepare the Quinoa or Rice: If you haven’t already, cook the quinoa or brown rice according to package instructions. Set aside.
4. Chop the Vegetables: While the chicken is cooking, chop the cherry tomatoes, cucumber, red bell pepper, and red onion. Set aside.
5. Slice the Chicken: After resting, slice the grilled chicken into strips.
6. Assemble the Bowls: In bowls, layer the cooked quinoa or rice first. Top with sliced chicken, cherry tomatoes, cucumber, red bell pepper, red onion, and Kalamata olives.
7. Add Feta and Tzatziki: Sprinkle crumbled feta cheese on top and add a generous dollop of tzatziki sauce.
8. Garnish: Finish with fresh parsley for a pop of color and flavor.
