Ideas to feed a large family for New Year's Eve.

[Titsalinabumsquash]

I'm having all my inlaws for New Years Eve, there will be 13 of us all together.
We don't have enough space for a sit down meal and usually I do a big pot of pulled pork and a roast gammon with salads and crusty bread.
I fancy doing something different this year but can't think what.
It needs to be something people can eat balanced on plates on knees so nothing saucy!
FIL requests nothing 'weird' or 'alternative' (when asked for an example he said Quinoa!)

How about something like beef wellington or salmon en croute? That is fairly easy to eat off your knees but also still a bit special ....
