Seafood - Smoked Salmon Watercress Salad With Red Onion Caper Vinaigrette

Start with a salad of smoked salmon and watercress. Try to buy the commercial bagged watercress that already has been cleaned to speed things along, or you may substitute other mixed salad greens. I like to make sure there are some bitter ones, such as radicchio and arugula, along with milder greens, such as butter lettuce or baby spinach. Also, because this is such a simple salad, all the ingredients should be top-quality. So spring for the best smoked salmon you can find.
