Polish sausage preparation

Hi guys I recently bought some polish sausage from a polski sklep. However it feels although it's already been cooked as it is fairly firm. Any advice on how to reheat please?

There are lots of kinds of Polish sausages. Some are cooked and meant to be eaten cold. If you're not sure whether yours is cooked, you can always steam for about 20 to 30 min in a covered frying pan with a little water in it.

Can you see any name?

Probably has been eaten ;)

I guess it is already cooked (smoked). To make it warm and tastier you can cut it along in halves and fry with onion.
