From Wikipedia,
Matzoh balls in a bowl of soup, Matzoh balls (Yiddish: קניידלעך kneydlekh pl., singular קניידל kneydl; also kneydls, matza balls, matzoh balls, or matzo balls) are a traditional Ashkenazi dumpling made from matzoh meal.
Your thinly veiled bigotry never ceases to amaze me.
I too wish you were smart enough to understand that never in the history of the world (or the hereafter) have Matzoh Balls been served up in a sandwich on Rye Bread. If you've ever had a well made Matzoh Ball in a bowl of Chicken Noodle Soup, you'ld know for certain that it would be found on any heavenly menu.
