I actually considered the dehydrator method. Some things we have would be so easy to use this way but its nothing I have done before. It is on the list of things to research though.
I am doing some stocking up but not tons. We do plan on sharing but only with family really. I have so much family in deep need that refuse to be responsible at all. They have kids, I can't let them go hungry. I won't pay their bills for them but I can provide food. We just about kill ourselves with the garden and such and the family just holds out their hands. Little frustrating at times. They are all curious how i am going to pasturize the milk from the cow so they can drink it. Ummm how to break this....
I am working really hard on frugal recipes, almost like depression era recipes. Almost everything is from scratch anymore. We have maybe 5% convenience foods at this point. I sorta feel like I live in the kitchen at times. Its hard to try to plan what things to stock up on.
We dehydrate a lot of things. We found mushrooms for 50 cents a pack and dehydrated them, both button and crimini. They work great in most things. We also dried some of our onions and all of the that extra summer squash. We tried it out in a couple of casseroles we've made and it works beautifully. We've also dried chicken, greens, apples, most fruits, etc ... Strawberries are great to dehydrate. They can be frozen after they are dried and then pulverized into a powder that you can mix with milk or yogurt for smoothies. Tomatoes can be dried the same way and pulverized for making into sauce later. The advantage is they take up a lot less storage space plus they last a long time, no freezing or refrigeration needed, thus no electricity.
