Boil ¾ cup of water in a small saucepan and cook ½ cup of quinoa according to package directions (about 15 minutes until all the water is absorbed).
While the quinoa is cooking, heat the olive oil in a large skillet over medium high heat. Add the corn and sauté until slightly charred, approximately 7-10 minutes. Transfer the corn to large bowl. Add the red onion, cilantro, and 1 cup of the cooked quinoa to the bowl. Mix to combine.
In a separate small bowl, add all dressing ingredients and whisk/stir until smooth. Pour the dressing into the bowl with the corn, toss to mix well.
Add half the dairy-free feta (or other dairy-free cheese of choice). Mix. Let the salad cool for at least 10-15 minutes. Add the remaining half of the cheese and mix. Garnish with more fresh cilantro and feta and serve!
