I have a friend from high school who is going to be shooting what he calls "a pro-animal rights terrorism" flick this summer. He eats blocks of tofu all of the time. (We're friends, he's just a kook.)
Now, if this were buffalo mozzarella, well, that is another thing entirely.
Tofu is no substitute for meat, I know. ;-) But it can be prepared so many ways, and is so tasty in it's own right...
