Drizzle the Victoria perch (or other fish fillet) with lemon juice and season with salt. Brush two pieces of aluminum foil that are not too small with liquid herb butter, place half of the fish fillet on top. Cut the white of the cleaned spring onions into oblique pieces approx. 1 cm wide and fry them in olive oil together with the ham cubes. Chop the washed parsley and fry for a moment. Spread the whole thing over the fish. Also distribute the sheep`s cheese cubes on the fish. On top of that comes a piece of herb butter.
Close the foil tightly over the fish. Bake in the oven preheated to 200 ° C for about 30 minutes.
