Tofu Stir Fry with Scallions

This was an incredibly simple and satisfying dish that I made tonight. From Mark Bittman's vegetarian cooking, it calls for:
1 1/2 pounds of extra firm tofu (drain before cooking)
3 tablespoon peanut oil
1 tablespoon garlic chopped
1 tablespoon ginger chopped
(2 dried chili, optional)
2 bunches of scallions
1/2 cup veggie stock or water
2 tablespoons soy sauce
(sesame seeds sprinkled on top, optional)
Cut the tofu into 1/2 inch or slightly larger cubes. Put the oil in a large skillet over high heat. When hot, add the garlic and the ginger and the chiles if you're using them and cook stirring for about ten seconds. Add the tofu and the white part of the scallions, cook stirring occasionally until the tofu begins to brown. Add the stock and cook, stirring until half of it evaporates, add the green parts of the scallions and stir for about 30 seconds.
Add the soy sauce , stir and taste adjusting seasoning.
I added a splash of peanut sauce (from TJS) which made it extra delicious. Next time, I might even use more scallions, ginger and garlic. This was a winner!
