Graham Crackers
Marshmallows
Any plain chocolate bar cut into pieces

Place a square of chocolate onto graham cracker. Place marshmallow on top of chocolate. Place another piece of chocolate on top of marshmallow and top with another graham graham cracker. Microwave on medium until marshmallow begins to  *grow*. Do not over cook. Or . . . at a campfire or backyard - do same procedure except roast marshmallow first. The warm marshmallow will melt the chocolate when squished together.
