DS2 reacts to Cambells (but he has a spice issue we cannot identify and Cambells was of little help).
I trust Progresso and have found them helpful for both boys (DS1 is gluten and egg allergic).
We also trust Gluten Free Cafe but could be ummm, interesting for those who are not gluten free.
I make my own most of the time (double batch) using Progresso broth but sans noodles, and freeze individual containers to have on hand.
