None of them. Buy ingredients from local supermarkets and package my own, the one exception being freeze dried meats mail ordered in #10 cans. Use sauces sold in the market, and measure to have just enough food to take one cup of water. But put sauce mix in a smaller bag inside the large one so that the more solid stuff can be boiled soft before the sauce powder is thrown in to simmer. Use a bag sealer so the package is just large enough to hold the mix. Have found this reduces both food volume and weight, and is much more tasty, as there is plenty of time at home to try ingredients and condiments before packaging them.
