I've never tried it, but there is a soy cheese version of parmesan available to buy online. It is fat free.

Also, someone asked about Xanthum Gum (Sandra, was it you?). They carry this also.
I've been buying soy cheese instead of ff cheese because I like the taste and consistency better. My grocery store has a brand called Veggie Shreds (shredded cheddar and mozzarella). According to the manufacturer's website, there is also a Veggie Parmesan, but I have not seen it in my local store and the online shopping for Galaxy Foods is "coming soon".
