It's so "rice" to meet a side dish that will have you running for seconds. The rice is only hot for a few minutes before it turns this great side dish into a cool offering. You'll love it either way.

Cook rice using package directions and let cool. Combine the rice, oranges, onions, celery, and mushrooms in a serving bowl, tossing to mix. In a small bowl, whisk together the rice vinegar, oil, and soy sauce. Pour dressing over rice mixture and mix gently. Chill until ready to serve.
