What's cool about marshmallows? "Even kids with food allergies can eat them," Krieger says. "Give one to a child who can't eat a chocolate chip cookie and you're sure to get a smile."
Four large marshmallows have 90 calories -- mostly sugar. To give 'em a nutrition boost, try skewering marshmallows with strawberries and other fruit.
Of course, toasted marshmallows and S'mores are American standards. If your kids haven't discovered these classic treats, it's time! Just toast a marshmallow over a grill or campfire, place it over a chunk of chocolate. Put it between two graham crackers (a good source of whole grains).
