Hi everyone, I found a pasta at HEB that is made of tapioca flour. It is in the Asian/International section of the store. I think the brand is “Elephant” something or other and has a picture of an elephant on the packaging. It's not exactly the same as regular pasta, but closer than mung bean noodles (which is also pretty good and in the same section in a hot pink netting packaging). I miss pasta, too! =)
I had also heard of yam noodles which you can get at an Asian grocery store (99 Ranch on Hwy 6 and Settlers Way). I think this one is in the refrigerated section, but ask around.
