vegan columbus: vegan living in central ohio

This is, hands down, my favorite dish from a chain restaurant* at the moment. I crave it, it's the only thing I order when I go there, and I've even gotten other people addicted to it. While it's very filling, at $8 a pop plus tip at the restaurant, here's an approximation to do at home with plenty for leftovers if you have more self-restraint than I do. I'm torn whether it's the amazing creamy sauce or the surprising tenderness of the silken tofu. The ingredients and directions were inspired by http://www.razzledazzlerecipes.com and, of course, P.F. Chang's, but composed by yours truly.
