Mix olive oil, garlic, lemon juice, oregano, paprika, cumin, salt, and pepper. Coat the chicken and marinate for 20–30 minutes.
Grill or pan-sear over medium-high heat for 6–7 minutes per side, until golden and fully cooked (165°F/74°C). Let rest for 5 minutes, then slice.
Blend or mix the Greek yogurt, feta, garlic, lemon juice, herbs, olive oil, salt, and pepper until smooth and creamy.
Fill each bowl with brown rice or quinoa and romaine lettuce. Arrange the cucumber, tomatoes, red onion, olives, avocado, and feta around the bowl. Add the sliced grilled chicken on top.
Add a generous dollop of the creamy yogurt feta dip, drizzle with a little extra virgin olive oil, sprinkle with fresh parsley, and serve with lemon wedges.
