Herdez is much too salty, IMHO. And whilst it doesn't address the original need, which was a salsa available in a supermarket, I would recommend Great Aunt Gerty's, which I have purchased at farmer's markets and garlic fairs. It is a bit sweet, to be honest, and not hot, with big chunks of tomato.
I don't know if the e-mail address works, or not, but I found
kcnet@magma.ca . If you have no luck, just serve Pace and lots of beer.
