I know Ashkenazi Jews don't eat "kitniyot", certain beans and the like, on Pessach.
Is tofu cheese included in that restriction? It's made primarily of soybeans.
Speak to your rabbi for a ruling and be sure that the product is certified for Pesach regarding the other ingredients.
Tofu is made from soybeans which are kitniot, so yes, tofu cheese would be included in the prohibition of kitniot.
