The Conservative Movement in the USA has ruled to lift the ban on kitniyos during Pesach. They point to the changing of composition of the Jewish community and its traditions as the reason for the lifting of the ban.

I have seen a couple of articles about this, but without too much explanation. They point to the increasing sefardic community in North America as the main factor.

The excitement among the followers of the Conservative movement seems to be focused on the ability to now serve sushi at the Pesach seder (and throughout Pesach).

Once sushi is on the menu, another idea for interesting change might be using the seaweed wrap for Karpas, and the Wasabi for Maror. Korech would just be a sushi sandwich in the matza.

Personally, I am still sticking to the traditional menus...
