As long as it's been refrigerated and isn't more than a week past the expiration date, it should be fine. Make sure it's the expiration date and not the "sell by" date. Those are two different things.
if it hasn't been opened, eat it
No, hence the word expired. It is unsafe to eat anything expired. Dispose of anything expired.
No. Pepperonis are too salty for hamsters.
YES! I just recently ate hummus, already opened, and it was expired. It didn't get me sick and it tasted the same as it did the first time I opened and ate it. So, yes, it is safe to eat hummus after the expiration date, opened or not.
pepperoni is considered non veg as it is a type of meat so i advise u not eat it as it is mostly unhealthy
NO, wth? its expired
Yes, all meats are a good source of protein. Eat pepperoni in moderation though, because it is high in fat.
only if it has been opened and then left out
Unopened pepperoni will usually stay fresh until shortly after their "sell by" date. Once opened, they might last around two weeks. They are expired once they have changed color to a very light orange.
If kept refrigerated, it should be safe to eat. Otherwise it should not be eaten.
Don't eat it. Mayonnaise is perishable.
