Herring à la Tomato Sauce

Since Finland has over 50 000 lakes, freshwater fish is the most common. There are salt water and freshwater herring. Use what you can find. 

I usually buy a can of herring in mustard sauce, placed in a sandwich with slices of cheese. I guess I could just buy herring in tomato sauce, but I tried a fillet.-Mike
