Late to this post, but couldn't resist. We keep graham crackers and a jar of Nutella and marshmallows in the trailer at all times. Nutella is easy to spread and does not need a fridge, and it doesn't melt. Always a good sub if you run out of chocolate bars...
Love Nutella!! Sadly, one of the kiddies tested positive for hazelnut allergy. Boo hoo! Can't keep it around anymore.
