Step 1: Marinate the Chicken
Mix olive oil, lemon juice, garlic, oregano, paprika, cumin, salt, and pepper in a bowl. Add the chicken and coat well. Let it marinate for at least 30 minutes (or overnight if possible).
Step 2: Cook the Chicken
Heat a skillet or grill pan over medium heat and add a little olive oil. Cook the chicken for about 6–7 minutes on each side, until golden and cooked through. Let it rest, then slice into strips.
Step 3: Make the Tzatziki
In a bowl, stir together the Greek yogurt, grated cucumber, olive oil, lemon juice, garlic, salt, and pepper until creamy. Taste and adjust seasoning if needed.
Step 4: Prepare the Veggies
While the chicken cooks, chop the cherry tomatoes, cucumber, red onion, and olives. Crumble the feta cheese if using.
Step 5: Assemble the Bowls
Start with a base of rice or quinoa. Top with chicken slices, chopped veggies, olives, tzatziki, and feta. Sprinkle with fresh parsley and add a squeeze of lemon.
