In a large bowl, whisk together the orange and lime juices, honey, cumin, oil, ¾ teaspoon salt, and ¼ teaspoon pepper.
Add the corn, tomatoes, jicama (if using), shrimp, pumpkin seeds, and scallions and toss well.
Made this salad for the first time for dinner this evening. It was a hit! I will definitely be making it again. Although I might try a little bit of cilantro & a splash Gran Mariner in it!
