Some friends are very kindly taking me to one of those operas with a posh picnic slot in the middle - like Glyndebourne. I said I’d do the picnic!
Any ideas? Needs to be served cold and, if possible, made in advance. Very limited time on the day. I am gluten free and one other has a legume allergy.
I was thinking of doing salmon, with a potato salad and some sort of veg, but would like a piece of salmon rather than those individual slices bur could do that.
