First we need to marinate the fish fillet for about half an hour. To do this, pour the fish with soy sauce and lemon juice.
Then sprinkle with salt, black and red pepper. Pickle for about half an hour.
Put potatoes sliced into thin slices at the bottom of the pan. Top with onions, sliced in half rings.
Salt, pepper, sprinkle with herbs and spices. Lay the fish on top. Then add the tomatoes and onions. Put the potatoes again and sprinkle the salt, herbs and spices on top. Pour the mayonnaise and sprinkle the cheese grated on a fine grater.
Place in the oven and bake at 180 degrees for about 45 minutes.
