Before buying a freeze dryer perhaps research to find out more about the downside of the machine; some people have problems with their machine and it's big and heavy and hard to return!
When trying to decide what to freeze dry you can start by asking why.
Start by asking yourself this question. Why are you freeze drying food? Knowing this should help you decide what you should freeze dry first.
I'm freeze drying because:
Just to freeze dry leftovers?
You want to make your own food for camping/backpacking?
For if/when the SHTF?
For a short term emergency?
You have your own garden and want to freeze dry the food?
You love Costco but don't have a family of 6?
You are good at finding the food sales but only have 1 freezer?
When you cook homemade chili just for yourself you make 10 gallons? Because you have 3 full freezers and are worried about power outages?

If I knew then what I know now, I would have freeze dried things in a different order. Or maybe not, because I started freeze drying because we had 3 full freezers, I was thinking of getting another one, and I decided I should buy a walk-in freezer instead. I started looking into walk-ins and realized they were expensive to buy (even used ones) AND expensive to own and operate. Then I found out Harvest Right was making home sized freeze dryers. One of my first thoughts was "I like Mountain House!" I have used their food for backpacking almost 45 years and we even kept some in our travel trailer, for just in case.

Freeze dried food will stay fresh for many years and be ready and waiting when you need it.
We do videos showing how we are using our Harvest Right Freeze Dryer to freeze dry food for long term storage. (We have the medium size machine that we got in August of 2017) We talk about how to load and unload the freeze dryer, how to know if the food is dry, is it better to freeze dry raw food or cooked food, and do a few taste tests. Freeze dried food is also great for prepping or just for camping and snacking!
