I always find chicken wings or drumettes a cheap and tasty finger food for parties and alot of people eat chicken but not other meats. Just marinate a kilo or 2 in honey and soy or satay sauce and bake for around 40mins, they are really yummy.

Other then that sounds as though you will have enough, if your family is like mine most of the males don't eat when they are drinking anyway.

Have a great barbie!!!
