It is basically pickled then olive oil added to it, so it is going to have a pretty long fridge life. Mine lasted in the fridge weeks, I am sure it can be canned, although I though that required heating, so it may change the texture. But for me, softer is better then crunchy for a sandwich like an Italian Beef!
I lika da juice...
Ya I was thinking this may get you the softer kind.
