I have foolishly agreed to hosting an after xmas get together for all the family as we cant all be together at christmas but have no idea what to cook. It will be for 8 adults. I want to do something that can be prepared in advance as dont really want to spend the whole evening in the kitchen. No special dietry requirements. Budget is middle of the road, want it to be lovely without being hugely expensive. Should add that i have never done this before! Any ideas??
