This Low Calorie Tartar Sauce is just 9 calories per 1/8 cup! Best of all, it's made with no mayonnaise, so it's actually good for you! And instead I use Greek yogurt (which actually boosts metabolism!)Special Tip: If you are wary of using Greek yogurt in place of mayonnaise, use 1/2 greek yogurt and 1/2 mayo (and omit the dijon mustard). It will still be much healthier and lower in calories than an traditional tartar sauce.
