If I had my druthers, salads would be made of nuts, cheese, and a fruity dressing with a few leaves of arugula sprinkled on top. Alas, those druthers miss the whole point of a salad, which "should" be a light, healthy meal. I'm not alone, though. Visit any restaurant, and you'll find salads packed with heavy (albeit delicious) add-ons, making them slightly less nutritious than a bag of Big Macs. But it doesn't have to be that way.
