Swap the mayo for mustard

The average yellow mustard contains 10 calories per tablespoon versus 94 calories per tablespoon of mayonnaise. Just implementing this simple ingredient swap can make your lunch sandwiches significantly lower in calories, without compromising on flavor. And if you want to try different varieties, whether it be whole-grain, Dijon or spicy brown mustard, the calorie count fluctuates only slightly, without going higher than 20 per tablespoon (don't hesitate to check the labels if you're unsure).
