Someone on this site recommended the pre-cooked bacon that comes in bags. You can find it in the isle where they sell salad croutons and bacon bits. I chose a bag of real bacon with picnic bacon. It was way to chunky for my taste. Next time I'll try the pre-cooked slices. I think it will keep for a long time unopened (check the date). Once opened I would use it up in a few days. Although I returned with my opened package after a week and it didn't have a strange odor but I was to affraid to eat it.
