Rinse quinoa thoroughly under running water in a fine mesh sieve. Combine with water in a saucepan, bring to a boil, then place a lid on top and turn the heat down to medium-low. Cook until the water is absorbed and the quinoa is tender, about 15 minutes. Meanwhile, combine all the ingredients for the Honey Lemon Vinaigrette in a mason jar or small bowl, then shake or whisk to combine. Set aside. Melt butter in a large skillet over medium-high heat. Add green onions and sweet corn, season with salt & pepper, then saute until corn is tender, about 3 minutes. Add in cooked quinoa and Honey Lemon Vinaigrette, then toss thoroughly to combine. Taste, add more salt & pepper if necessary, then serve.
