2 jars (450 g each) of interesting food from Poland. Technically it is a ready meal (just to be cooked by bringing it to legal temperature – boiling hot) but I would personally recommend giving it 20-30 minutes of further simmering just to make the meat tender. I have also added some tomato passata (as in the example of serving idea) but this is quite optional.
