In a medium saucepan, bring the vegetable broth or water to a boil. Add the rinsed quinoa, reduce the heat to low, cover, and simmer for about 15 minutes or until all the liquid is absorbed. Remove from heat and let it sit covered for another 5 minutes. Fluff with a fork and let it cool completely.
In a large mixing bowl, combine the cooled quinoa, cherry tomatoes, cucumber, red onion, Kalamata olives, feta cheese, parsley, and mint.
In a small bowl, whisk together the olive oil, lemon juice, dried oregano, salt, and pepper to create the dressing.
Pour the dressing over the quinoa salad mixture and toss gently until everything is well coated.
Adjust seasoning with more salt and pepper if needed.
Let the salad sit for about 15 minutes to allow the flavors to meld before serving.
Notes
Let the salad sit for 15 minutes before serving to enhance the flavors.
