Marshmallows, Chocolate Graham Crackers, and Dark Chocolate Reese's Peanut Butter Cups! I also had original graham crackers and Hershey's Milk Chocolate bars for the purists.
I couple years ago I was at a cute restaurant that served smores at the table. They had a small grill and brought a plate pf the ingredients to the table. It was so cute! I purchased a hibachi grill and use canned sterno with skewer sticks and get the same effect. It is so much fun, portable, and ready-to-go at an festive time.
