Cook quinoa according to package instructions, using 2 cups of water. Once done, fluff with a fork and let it cool completely.
While the quinoa cooks, prep your vegetables. For the cucumbers, I recommend removing the seeds if they're particularly watery.
In a small bowl, whisk together the olive oil, lemon juice, minced garlic, honey, salt, and pepper until well combined.
In a large bowl, combine the cooled quinoa, diced cucumbers, red onion, cherry tomatoes, mint, and parsley.
Pour the dressing over the salad and toss gently to combine.
If using, sprinkle crumbled feta cheese on top just before serving.
