In a medium saucepan, combine 1 cup uncooked quinoa, 2 cups low-sodium chicken broth, and 2 smashed garlic cloves. Bring to a boil, reduce heat to low, cover, and simmer until the liquid is absorbed. Remove from heat, let stand covered 5 minutes, discard the garlic cloves, and fluff the quinoa with a fork.
While the quinoa is cooking, heat the 22 oz diced chicken breast (Tyson Grilled & Ready) according to the package instructions until heated through; set aside to cool slightly.
In a large bowl, combine 3/4 cup diced red onion, 3/4 cup diced red bell pepper, 1/2 cup chopped kalamata olives, 3 tbsp chopped fresh parsley, 2 tbsp chopped fresh chives, and 1/2 cup crumbled feta cheese.
In a small bowl, whisk together 2/3 cup fresh lemon juice and 1 tbsp balsamic vinegar. Slowly whisk in 1/4 cup olive oil until the dressing is combined; set the dressing aside.
Add the fluffed quinoa and the heated chicken to the bowl with the vegetables, herbs, and feta.
Pour the dressing over the salad and gently toss until everything is evenly coated and thoroughly mixed.
Serve immediately or refrigerate and serve cold.
