Good advice on the trying it thing before investing a lot. I recently discovered knorr sides at Walmart. I tried one pasta dish and it was really good, so I bought a couple of each flavor they had the next trip. The next one I tried went to the dogs after two bites....Mountain House makes some decent dehydrated meals. Granted, I think they were about $5 at Walmart, but really, enough for two people, so figured that way, it isn't too, too bad, for price on survival food. If you do something like this, be sure to actually TRY each flavor before buying multiples.
Personally, I like these more when size and weight are an issue (like in your bug out bag, or get home bag). I'm more partial to the beef stew one myself.
another thing brought up was the compact and light portability of freeze dried meals. Canned goods are great at home or bol, but suck to carry.
