Fresh and full of superfoods, this salad will boost your immune system—but all you will know is that your taste buds are dancing in delight. For less of a kick in the dressing, substitute yellow mustard for Dijon. For a heartier kick, sub with horseradish mustard. The varieties of mustard are so plentiful that you can enjoy a different salad each time. This meal is also great with cod, shrimp, or even lobster!
