I grew up in an Ashkenazic non-Orthodox home in rural Maine. Passover was a consistent experience during my childhood. We refrained from eating chametz and kitniyot (legumes, rice and other items which Askenazic Jews traditionally don’t eat on Passover). I never questioned our tradition.
As a vegan single woman in my 20s without children, my Passover food focus was potatoes, sweet potatoes, squashes, vegetables and fruits. I did of course eat matzah but even then I limited the amount every day because too much matzah makes me feels constipated during the holiday.
This felt fine to me at the time, as I am a person who loves potatoes, simple foods and rules. For me, Passover is a physical experience and simplifying my diet is a way of experiencing freedom.
