Rinse the quinoa under cold water. In a medium saucepan combine quinoa and water or broth. Bring to a boil then reduce to a simmer and cover. Cook for about 15 minutes or until quinoa is fluffy and water is absorbed.
Combine the cooked quinoa, cherry tomatoes, cucumber, bell pepper, corn, red onion, and parsley in a large bowl. Toss lightly.
Whisk together the lemon juice, olive oil, salt, and pepper in a small bowl. Pour the dressing over the salad and mix well.
Chill in the refrigerator for at least 30 minutes before serving. Enjoy as a refreshing side dish or a light main meal.
Notes
This salad keeps well in the fridge for 3-4 days, and the flavors improve over time. You can add protein like chicken or tofu to make it a more substantial meal.
