Spread out the ready-made pizza dough thinly onto a tray. Cover with aluminum foil to prevent it from rising and bake it. Separately, in preheated oil, fry salmon fillets- you just need enough to cover the dough, season them with salt and pepper and arrange on the dough.
In a separate pot, stew the spinach and then spread it over the fish. Beat the eggs with milk and cream and pour the mixture oven the entire dish.
Bake in a preheated 302°F (150°C) oven for about 20 minutes. The salmon can be substituted with another fatty fish.
