Thaw the frozen salmon fillets. Cut the onion and tomatoes into small pieces. Wash the spinach.
Cook the rice according to the instructions on the packet.
Fry the salmon fillets in a pan in the oil on both sides and season with pepper. Take the fish out of the pan and possibly keep it warm in aluminum foil.
Steam the onion in the same pan at medium or higher temperature until translucent. Add the tomatoes and fry briefly. Deglaze everything with wine and simmer for a few minutes. Fold in the spinach under low heat until it has collapsed. Stir in the cream, season everything vigorously with salt and pepper.
At the end, briefly return the salmon fillets to the pan and sprinkle the crumbled feta cheese on top.
Then arrange the dish with the rice on plates.
You can also enjoy baguette, salad or the rest of the wine.
