Preheat the oven to 400 degrees F. Grease a glass baking dish with butter. In a small mixing bowl, combine the bread crumbs, parsley, and cheese. Season with salt and pepper. Mix well. Set aside. Season the potatoes and onions with salt and pepper. Place a layer of potatoes on the bottom of the prepared pan. Place a layer of onions over the potatoes. Sprinkle 1 tablespoon of the flour over the onions. Place half of the herring over the onions. Repeat the layering process with the remaining potatoes, onions, flour, and herring. Pour the milk over the herring. Sprinkle the top with the bread crumb mixture.
