Stuffed cabbage rolls originated in the Ottoman (Turkish) Empire as stuffed grape leaves. They were brought to Eastern Europe with the Ottoman Army and re-invented with local ingredients, i.e., cabbage instead of grape leaves. So it's Eastern European, not just Polish. I suppose Ashkenazi Jews picked it up, too, since it doesn't violate any dietary laws that I know of.
