About 20 years ago, I went to Finland to visit a friend and I had the opportunity to stay with her and her parents.
They treated me with home-made meals. It was really good.
I remember that they have a special bread which serves as a meal. It was filled with small fishes and an unknown sauce. When you cut it open, the content was flowing outside of the crust.
I asked my friend about it but she couldn't find an answer. I'd love to find the name of that bread / dish.
