01 - Combine olive oil, garlic, oregano, smoked paprika, cumin, lemon juice, salt, and pepper in a bowl. Coat chicken breasts thoroughly in the marinade and let sit for at least 15 minutes to absorb flavors.
02 - Bring quinoa, chicken broth, and salt to a boil in a saucepan. Reduce heat to low, cover, and simmer for 15 minutes until all liquid is absorbed. Remove from heat, fluff with a fork, and set aside.
03 - Preheat grill or skillet over medium-high heat. Cook marinated chicken breasts for 6 to 7 minutes per side until internal temperature reaches 165°F. Let rest for 5 minutes before slicing thinly against the grain.
04 - Whisk together extra-virgin olive oil, fresh lemon juice, honey, Dijon mustard, salt, and pepper in a small bowl until emulsified and smooth.
05 - Divide cooked quinoa evenly among four serving bowls. Arrange sliced chicken, cherry tomatoes, cucumber, red onion, Kalamata olives, and feta cheese on top. Drizzle with dressing and garnish with fresh parsley.
06 - Serve bowls immediately while chicken is warm, or allow to reach room temperature for a refreshing cold meal option.
