A ways back I was at a gun show and a guy was selling MREs. He had some snack type items out for people to try. Various crackers, cakes, PB, cheese, maybe some other things. I sampled what he had out. I was unimpressed. They were all edible but not especially good.
I bought one entree and ate it at home. Don't recall what it was. Some kind of pasta dish of some sort IIRC. Or maybe rice. I was unimpressed with it as well.
These are not made for anything other then sustainment, portability, and long term storage. They do that well. Tasting good was never part of the criteria.
Personally, I have often wondered why the military never made some kind of ration heater that would fit around standard cans of food. Just issue the ration heaters and canned foods off the shelf. Would have a much larger variety and much cheaper. It would not be any heavier, or bulkier.
