In a saucepan over medium heat, bring the vegetable broth to a boil.
Add the rinsed quinoa to the boiling broth. Stir, cover, and reduce the heat to low. Cook for about 15 minutes or until the quinoa is fluffy and liquid is absorbed.
Once the quinoa is cooked, remove it from the heat and let it sit, covered, for 5 minutes.
In a large bowl, combine the drained chickpeas, halved cherry tomatoes, diced cucumber, chopped red onion, sliced olives, and crumbled feta cheese.
In a small bowl, whisk together the olive oil, lemon juice, dried oregano, salt, and pepper to make the dressing.
Fluff the quinoa with a fork, then add it to the large bowl with the vegetables and chickpeas.
Pour the dressing over the quinoa and vegetable mixture, gently tossing to combine everything evenly.
Adjust seasoning if necessary, and top with freshly chopped parsley before serving.
Notes
Serve in individual bowls, topped with extra feta and a sprig of parsley for a colorful look.
