1. Sauté the spinach in a pan with a little water (follow the instructions on the package) until wilted. This should take about 10 to 15 minutes.
You can also use a large can (about 800g) of canned chopped spinach. In this case, drain the can in a colander and press the spinach with a fork or other utensil to remove as much water as possible.
Season with salt and pepper.
2. Meanwhile, in a large bowl, mix the eggs with the sour cream, a little salt and pepper, and 30g of grated cheese.
3. Preheat the oven to 180-200°C (350-400°F).
Cut the salmon fillets into small cubes (remove the skin) and add them to the bowl with the spinach. Mix everything together.
4. Prepare your pie crust in a pie dish, prick it with a fork, and pour the entire mixture onto it. Spread it evenly over the entire pie crust.
Sprinkle with a little grated cheese (about 20g).
5. Bake for about 40 minutes at 180-200°C (350-400°F).
