Rub the chicken with olive oil, garlic powder, oregano, paprika, salt, and black pepper.
Heat a large skillet over medium-high heat.
Cook the chicken for 6 to 7 minutes per side, or until it reaches an internal temperature of 165°F (74°C).
Let it rest for 5 minutes, then slice.
Whisk together the olive oil, lemon juice, Dijon mustard, honey, oregano, salt, and black pepper until smooth.
Divide the rice or quinoa, romaine lettuce, tomatoes, cucumber, olives, hummus, and feta cheese among serving bowls.
Top each bowl with the sliced chicken.
Drizzle the lemon dressing over each bowl.
Sprinkle with fresh parsley and serve immediately.
