If you are hesistant about canning or dehydrating your own foods, you can always order from sites that already have done the work for you. I will warn that not all are inexpensive as home preservation but are convenient if you don't have the time. I found a few sites that you can explore and see what will best fit your needs.
Shelf Reliance - I saw a commercial on the BYU channel just after Conference a few months ago, they have a lot of good things.
My Food Storage Chef - I saw an add on Facebook and ordered a sample, can't wait to see what I get to try it out!
Provident Living - this is the LDS Church sponsorsed website to become self reliant. It has tons of good info.
You can also order from your ward canning specialist and volunteer at the local cannery in your area for items you need.
