My wife and I's seafood collaboration dinner
I've never known what the proper way to use a sentence in which you and a specific person (as in you can't just say "our" because you want to specify who) possess something. Is it "Julie's and mine", "Mine and Julies", "Julie and my"...?
For instance, "Julie and my favorite band is Eluveitie." "That sandwich is Ben and mine."
They all sound a bit strange, which is the correct way to say this?
