I love this recipe! I love adding pretzels! I have also tried low fat graham crackers, too. It really feels decadent! It is chewey and satisfying with the marshmallows...the added crunch from pretzels or graham crackers adds another dimension that sends it over the top! I am going to investigate whether using other kinds of chips would make a significant point value difference because the bittersweet or even semi-sweet chips are intense (but maybe that's the idea, right?!). Good recipe!
