Since the mixture is already seasoned, simply place it on the greased baking sheet, smooth it out and bake in a preheated oven at 200 ° C for about 15 - 20 minutes. Take the tray out of the oven and cover with sliced smoked salmon, sprinkle with grated cheese. Again for about 30 minutes (until the cheese is crispy and golden yellow) in the oven. Finished.
