I think that's what the konnyaku threads are called. You have to parboil them for about 5 minutes before you add them to anything, or they taste funny. The nice thing about them is they will absorb the flavor of whatever broth you cook them in, which makes them better than noodles! I think they are the ultimate LC food.

Besides, all the "nice" low-carb goodies can get you into trouble. Those Atkins bars did me in until I found out that the 2g on the package isn't necessarily what my body reacts to...
