Preheat oven to 375 degrees Fahrenheit(190 degrees Celsius).

In a 9- x 13-inch (23- x 33-centimeter) baking pan, combine the quinoa with water, juice, oil, honey, salt, and pepper, mixing gently. Bake uncovered for half an hour, stirring once during that time.

Cool to room temperature and add orange segments, nuts, and greens before serving.
