Start by rinsing the quinoa under cold water to remove any bitterness. In a medium saucepan, combine the rinsed quinoa and chicken broth. Bring it to a boil over medium-high heat. Once boiling, reduce the heat, cover, and simmer for about 15 minutes or until the quinoa is fluffy and the liquid is absorbed. Remove from heat and let it sit covered for an additional 5 minutes.
While the quinoa is cooking, heat a skillet over medium heat. Add the diced chicken breast to the skillet and sauté for about 5-7 minutes, or until heated through and slightly browned. Don't forget to add the smashed garlic cloves while cooking for additional flavor.
In the meantime, chop the red onion, red bell pepper, kalamata olives, fresh parsley, and chives.
In a small bowl, whisk together the fresh lemon juice, balsamic vinegar, and olive oil. Season with salt and pepper to taste.
In a large mixing bowl, combine the cooked quinoa, sautéed chicken, chopped vegetables, and herbs. Drizzle the dressing over the top and gently toss everything together. Finally, sprinkle the crumbled feta cheese on top and give it one last gentle toss to combine.
