Oh wow, thank you all so much! I'm going stick all of these ideas in a word doc to refer to.
Probably something buffet wise would be better due to numbers (she lives in a big house but probably not that big

Ooh, I'm so glad I posted now! 

Mrs JMP:
Beetroot mash & pink salmon fish cakes

How fab does that look?!
