These Low Calorie Soft Pretzels is just 105 calories for one small pretzel, or 210 for a large pretzel.I like to serve the small pretzels, they are the perfect amount of calories for a snack and quite fulling. Try serving them with cheese sauce (recipe above) or mustard. Special Tip: It is VERY IMPORTANT that you use self-rising flour to make these healthy pretzels. All-purpose flour will not work in this recipe.
