I used these rations quite often as they are light weight and very neat to pack. It doesn't produce "messy garbage". Just roll up the package and seal it in a ziplock pack. Very little mess.
They actually taste very good, but they are not very "meat heavy" even if it is a meat dish. While the package said "2 portions", it is really for one person after a day of work. I also find that they like a bit more water than indicated.
