I read the Rav’s teshuva on Quinoa being considered kitniyos on Pesach. What does the Rav hold about Chia Seeds?
Quinoa has traditionally and is still currently used as a staple type food, similar to rice and corn. It is eaten not only as a topping or additive but also as a dish by itself. Chia seeds however have are not used as such. Rather they are generally used a topping or additive, mostly for their nutritional value not for their taste or satiation. Hence they do not fill the criteria of grain like foods which are included in the prohibition of kitniyos, and are permissible for consumption on Pesach.
