Steps
1. In a bowl, combine olive oil, lemon zest, lemon juice, minced garlic, oregano, salt, and pepper. Add chicken breast and marinate for at least 15 minutes.
2. Rinse quinoa under cold water. In a small pot, bring water to a boil, add quinoa, reduce heat, cover, and simmer for 15 minutes or until water is absorbed.
3. While quinoa cooks, heat a grill pan or skillet over medium heat. Cook chicken for 6-7 minutes per side or until fully cooked and juices run clear.
4. Fluff cooked quinoa with a fork. Mix in cherry tomatoes, cucumber, parsley, olive oil, and salt.
5. Plate the grilled chicken alongside the quinoa salad and serve immediately.
