Southwestern Quinoa and Black Bean Salad

A relatively simple salad that came about when a friend gave me a box of red quinoa. After cooking it, I started adding ingredients that I had on hand, starting with the beans (I almost always try to mix grains and beansns for the nutritional advantages). I considered adding a cream or cheese sauce but this would have required a trip to store and it was 12 below and windy outside (Elgin, IL). So I mixed up a quick vinegar and oil dressing and this is the result.
