Tuna Fish is on the way...and no, I don't have a problem serving it plain WITHOUT mayonnaise. Actually that would be easier and mayo is already supplied at the side 'condiment' tables in the dining room.
But, I can not guarantee that somebody from salads will not do it...because I want them to have some creative freedom to produce salads (and sometimes that will include mayo).
I think it will arrive at least by late March, maybe earlier. Depends on containers.
