Family is coming over for 6 days idk what to cook for 15 people

A final Q: are you in a city and, if so, is this their first visit? If this is the case, I strongly suggest that the entirety of day 1 be spent sightseeing, which knocks all three meals for that day out.

Heh, you've seen me answer these before, eh? I don't know why, but I get an odd pleasure from doing them.

First figure out what kind of bread you want to bake, then figure out the salad.
