My grandmother gave me one of those vacuum sealer thingies, which I have yet to try out. But I was wondering what I can repackage down from bulk, and what I need to buy in small packages.

Specifically, summer sausage. I have a foot-long stick (Hillshire Farm), but that's way too much for one meal. Can I cut it into three or four pieces and vacuum seal them? How long will that be good?

What about items in cans? Pineapple, olives, etc.

Some things are pretty obvious. Like minute rice, couscous, etc. Those are shelf-stable and should be ok. It's the canned "refrigerate after opening" stuff I'm curious about.

Thanks for the help!
