The makers of [url="http://www.chreese.com"]Chreese[/url] have proclaimed on their website that they are [url="http://www.chreese.com/special_other.php"]completely nut-free[/url] .
i'm not vegan, but i like chreese. the spicier version (in the penne boxes and the individual chreese packets) is pretty tasty. the nacho chreese is also good.
all chreese products are vegan, they have a page on their site listing the kosher certifying organization they use, and they have wheat/gluten-free products, too. (not all of them are GF.)
i thought some folks here might be interested.
