Some kosher and Passover stuff I found...
Finally, there is one product called "quinoa" (pronounced "ken-wah" or "kin-o-ah") that is permitted on Passover even for Ashkenazim. Although it resembles a grain, it is technically a grass, and was never included in the prohibition against kitniyot. It is prepared like rice and has a very high protein content. (It's excellent in "chollent" stew!) You should be able to find it at most health food stores. Of course, it needs to be from a closed container that is new for Pesach.
And...
While quinoa was first imported to the United States from Chile in the 1980s, it was only deemed kosher for Passover in 1999 when Star-K’s Rabbi Shmuel Heinemann responded to a customer's inquiry. Rabbi Heinemann discovered that quinoa, a sesame-seed looking kernel reminiscent of rice, is not a grain. Quinoa is a member of the beet family. When Star-K tested quinoa to see if it would rise, they found that it actually decayed. Furthermore, Rabbi Heinemann determined that quinoa is not kitniyot. It does not grow in the vicinity of chometz and its growth does not resemble kitniyot. And it has no religious precedent included in the prohibition against kitniyot.
While I know what NONE of this means, it seems like quinoa is allowed for passover.
