I'm vegan, and probably not. I've heard that most vegan substitutes are processed heavily so not really more healthy (and probably less healthy than non-vegan options).
However, I do still eat them on occasion. Sometimes after a 30km run, all I think about is burgers so when I get home and sit and have vegan burger with vegan cheese.
It may not be as good as the 'real thing' but it hits the spot :)
