The nice thing about using quinoa, a whole grain found in most natural grocery stores, in this tabbouleh-style salad is that it doesn’t soak up all the dressing and dry out over time.
1. To make Quinoa Medley: Bring 2 cups water to a boil in medium saucepan. Stir in quinoa, cover, and reduce heat to medium-low. Simmer 15 minutes, or until quinoa is tender and opaque, and liquid is absorbed. Let stand 5 minutes, then transfer to large bowl. Fluff with a fork, and cool.
2. Fold corn, zucchini, green onions, cilantro, and mint into quinoa.
3. To make Dressing: Whisk together oil, orange juice, lemon juice, and orange zest in small bowl. Season with salt and pepper.
4. Drizzle Dressing over quinoa mixture, and toss well. Sprinkle with pine nuts, garnish with mint sprigs, if desired, and serve at room temperature.
