Instead of cod fillets, you can use fresh/fresh-frozen zander or catfish fillets in this recipe. But the second fish must be hot smoked.
Wash the lemon, cut into thin slices. Cut fresh and smoked fish into pieces, commensurate with lemon circles.
Sort all the greens, wash, dry and finely chop; mix. With a mixer, beat the egg with cream and wine; salt, pepper to taste. Preheat the oven to 200ºС.
Put half of the chopped greens on the bottom of the baking dish. Then put pieces of fresh fish, lemon slices, on top - pieces of smoked fish and the remaining greens. Pour the sauce over the fish and cook in the oven at 180°C for 10-12 minutes. Serve hot.
