I am what Jewish people call a “balabusta.” Which is a yiddish term generally meaning something like a woman who likes to cook, is energetic and keeps herself busy with a lot of different things.
So preparing for Passover and cooking an entire dinner for anywhere from 14 to 30 people never seemed daunting to me.
But I also realize that while being a “balabusta” always worked for me, it is not every woman’s goal. Many many women have absolutely no interest in cooking, no less for a crowd of guests. Or they have absolutely no time or are too busy with kids or elderly parents or whatever it is that takes up a life. They need help if they are having a Seder at their house.
Sometimes a local kosher catering place has a special Passover menu. Sometimes you can order through your synagogue. If you live anywhere near Fairway (there’s one where I live in Stamford, CT.) you can order from their menu: http://www.fairwaymarket.com/files/catering/fairwaystamfordkosherforpassovercateringmenu2012.pdf
It’s a traditional Ashkenazi style dinner, complete with matzo ball soup, gefilte fish, brisket, potato kugel, etc. and you can order a complete dinner or a la carte items.
