You can fairly easily can meat, similar to bottling vegetables. I have done it with cubed pork (it's what people in Germany used to do before freezers!), great quick dinner made with it as well, as meat is already cooked and only needs adding some chutney, creme fraiche, mustard and about 20 minutes in the pan.
When I get a minute I write up the procedure, it definitely saves on feezer space!
