In a medium saucepan, place the wild rice. Add the water or broth and bring to boil. Reduce the heat to low, cover and simmer for 50 minutes or until the rice is tender. Drain if needed and let the rice cool.
Make the dressing: In a small bowl, whisk together the olive oil, lemon and orange juices, mustard, honey, sea salt and pepper.
Place the cooled wild rice in a large bowl. Add the arugula, chopped scallions, mango, radishes and arugula. Add the dressing, stir well, and adjust seasoning to taste. Store in the refrigerator, covered, for up to three days. It tastes best when given at least an hour to marinate before serving.
Enjoy!
