Make the dressing: In a small jar, combine the ingredients listed below. Either use a fork to whisk the ingredients well or screw a lid on the jar and give it a few good shakes. Taste the dressing and adjust the flavors if necessary (add vinegar for a more tart dressing, or maple syrup for a sweeter dressing). Set the dressing aside.
Cook the quinoa: Note that 1 cup of dry quinoa yields over 3 cups cooked quinoa. Rinse the quinoa well in a mesh colander, then combine the rinsed quinoa with twice as much water in a saucepan. Bring to a boil, cover and reduce heat to a simmer. Cook for 15 minutes or until water is absorbed, remove from heat and fluff with a fork.
