Cook the quinoa according to package instructions.
Once cooked, set aside and let cool.
In a large bowl, combine the cooked quinoa, black beans, corn, avocado, cucumber, cherry tomatoes, and chopped parsley leaves.
In a small bowl, whisk together the lime juice, olive oil, salt, and pepper.
Pour the dressing over the quinoa salad.
Toss gently to combine.
Let the salad chill in the refrigerator for at least 30 minutes to allow the flavors to meld together.
Serve chilled.
Enjoy!
