Hollywood stars like Mandy Moore know that when it comes to sandwiches, less isn’t more. If you skip the mayo but add a little coleslaw to your sandwich, you’re only packing another 50 calories. A huge scoop of slaw, however, delivers a walloping 200 calories. Also, it’s good to add tomatoes to your sandwich because they contain lycopene, a cancer fighter that also helps you fight off heart disease. Mustard has only nine calories. As for cheese, cheddar is better than provolone because you save upward of 70 grams of salt. If you want to save calories, skipping any full-fat cheese will reduce your luunch by a major 100 calories. Skip the pickles or you might as well suck on a saltshaker.
