Mountain House Chili Mac #10 CanBy far the best food storage money can buy, Mountain House freeze-dried foods usually require only boiling water to prepare. Light weight and easy to store these tasty foods have an incredible 25 year storage life according to the people at Oregon Freeze Dry, Inc. When we look at the unstable stock market, world wide tensions and natural or man made disasters and the sliding dollar. A little insurance could go a long way in an emergency or even a job loss. Our unique canning process uses both vacuum oxygen removal and nitrogen flushing. This is a time consuming and slightly more costly process...but well worth it. It is the same process mandated by the U.S. Military.
