I just recently been to a party so I'll just list the food we had there :P

Sausages/ Sausage rolls, Quiche, Cold pasta with a tomato sauce in it, I always think it tastes nicer cold :P, Lots of finger food like chicken nuggets, bbq chicken pieces and loads of sandwiches! I always think that breadsticks and dip or pringles and dip is nice for finger foods. There was also a delicious fruit salad that was just simply strawberrys, Melon and grapes!
