Udon with Shiitakes, Greens, and Tofu

This is a Veganomicon recipe, mostly. I added tofu for protein, and used turnip greens because the grocery store was randomly out of the called-for kale. I'd never tried turnip greens but they were basically the same as kale or collards or whatever - maybe just a little flimsier.

The recipe called for serving it with a lot of broth, kind of soupy, but I decreased the liquid and made it more like a stirfry. The sauce is just mirin, soy sauce, miso, and water. Kind of a nice sweetish flavor.
