The Passover menu suggestions so far are some of the most common (= popular) dishes among Ashkenazi Jews -- those of us descended from Eastern Europeans. Since that's a majority of Jews in much of the U.S., it's hard to go wrong with them. This is the one time when people who wouldn't touch it otherwise might eat brisket cooked in kosher-for-Passover Coca Cola.
But for something a little more unusual, have a look at some of Joyce Goldstein's recipes. She has a couple of books on Italian and Mediterranean Jewish (Sephardic = eastern) cooking. I've used recipes from
Cucina Ebraica at home, and they're great!
