Some of the reviews of Hormel Completes I read online made me snort, but there are clearly enough people interested that they continue to sell. If it makes you happy, it won't kill you any faster than McDonalds.
Take a look at Bear Creek Country soups and pasta packages. All you need to do is boil water and add. I have taken packages and divide them up into single serving units and store in a sandwich bag. Very tasty, especially if I have some leftover chicken or something else in the cooler.
I have also been reading up on the backpacking cookbooks for ideas that are quick and
light and don't require refrigeration.
