WOW! 30 16 yr. olds.... hmmmm.... anything not nailed down will be eaten. Do a BIG potato salad to, starchy and filling. Take 6 loaves of french bread, cut in half, baste with mix of melted butter, fresh minced garlic, cummin and sprinkle a little paprika on them - then toss on a hot grill for a few minutes to brown.
Good luck! And make sure no fingers are lost in the feeding frenzy!
