We actually have this conversation a lot around my house.
I would have:
My grandmother's deviled eggs, pork chops, green beans and mashed potatoes with gravy and possibly also her potato salad.
Literally, that is what my grandmother would make me all the time when I went over to her apartment for dinner. The love that was contained in that food, still to this day, overwhelms me. Now, because it could never be duplicated by anyone else... and because that is what I would want only if SHE were able to make it, I would have this instead:
Sushi. Omg. Platters and platters of sushi. And sake to drink. And water. Amen.
