Sherry, there was a zone tip floating around a few years ago that recommended Progresso's beef barley soup as a zone-favorable meal. Now, at this time, I am unable to recall exactly which variety that was (I think there is more than one), but if you read labels, you can probably figure it out.
You can also balance a few frozen dinners, but again, important to read labels, and you may need to add in some protein or fat to balance them thoroughly.
Cedarlane Foods has a line of Zone frozen dinners, but I have not seen them in stores for some time. However, you can probably find them online at www.cedarlane.com
