S'mores have long been a favorite dessert for folks sitting 'round a campfire. Fortunately, a hot grill can easily do the job of melting marshmallows even when there's no fire in sight. Spear marshmallows on wooden or metal skewers, then hold them over the grill until you achieve just the right blend of gooey center and toasted outer shell. Sandwich the marshmallows between two graham crackers, and add a square of chocolate or two to create a sticky, sugary treat. Add a unique twist to this dessert by replacing the chocolate with a peanut butter cup or swapping the graham crackers for a pair of chocolate chip cookies.
