Taken literally, as "with rice", I suppose you could put anything with the rice and call it sushi. But you are not going to like the look you get from me if you place western food on a lump of rice in front of me.

Pickles and carrots - ok, if its oshinko.
If its kosher dill, I would eat it, but think you lost your mind.
If its a sweet or butter pickle you better duck because it may be airborne rather quickly.

I side with Yuujiro - there are traditional boundaries. You don't adulterate my sushi with cooked ground beef, and you don't mess with my chicken fried steak & cream gravy by serving it with miso on the side.
