Mayonnaise is the go-to condiment for nearly every sandwich, the base for countless dressings, and the “glue” that holds together chicken, turkey, and tuna salads. No wonder America is so fat; mayo is also one of the most calorically dense, and nutritionally empty, foods you can eat.

For most recipes, one easy ingredient swap can give you the satisfaction of your favorite lunch foods with up to half the calories. Not only will you also cut your fat intake in half, but with many of the substitutions suggested here, you’ll also reap the benefits of additional fiber and protein. Throw away your mayo and give your waistline a break—not to mention a better tasting lunch.

Changing just two ingredients from the traditional chicken salad recipe cuts calories by more than half while keeping protein and fiber the same.
