I don’t have any suggestions, I’m sorry. We went no sodium when my mother and grandmother (and, actually the other grandmother, too) were diagnosed with various things that required low sodium. I did not like it at all (it also coincided with going low fat, so between losing salt and fat, it was agony.
BUT what my mother and grandmother’s didn’t have was the internet!
