I use the stuff from HEB too. It is only abour 3 bucks for a very large pack. It is roasted. I drop some Selcon and garlic on it and let it soak for a few minutes first. Then I bind it to a rock using a rubberband. I have been doing this for about a year. The tangs love it and my wallet does too. 10 healthy tangs can't be wrong. Thanks Pete for turning me on to it.
