As I finish my lunch, a Banquet frozen meal, specifically the “Turkey meal” I note that is must be healthy as it contains 61% of my recommended daily allowance of sodium: 1460 mg.
However, it does seem that Banquet could probably just cut that salt in half with minimal effect on taste. I could always reach for the ever present shaker, if I needed more.
(Hard to remove the salt that the manufacturers put in, but easy to add it at the table)
Salt is a preservative so I doubt if they could easily remove that salt and have the package stay fresh for the same duration.
