Cooking over fire always keeps kids busy. At any time of the day, my teenage boys and their friends are ready to eat so you could have hotdogs and buns with ketchup and mustard available and that will keep half of them happy.
At one of my teens' parties I put together a tray of different smores fixings. Instead of the plain old hershey bars they combined marshamallows with snickers, kitkats, and other chocolate. Along with graham crackers we had chocolate covered pretzels, chips ahoy cookies, etc. I think I even found different flavored marshmallows to put on the tray. It was all just goodies I found at Target but it was pretty fun and yummy to make different combinations.
