I'm not sure if this is in the right place but I wanted to make Alton brown's protein bars without using any soy. recipe can be found by clicking here. A whey for soy powder substitution is easy but I cant think of anything that would be an appropriate substitute for tofu. Alton won't write me back (yup, i tried asking him, and all I got was an automated response a couple weeks later about how busy he is). Any ideas?
