Preheat the oven to 200 degrees top / bottom heat.
If necessary, wash the fish fillets and pat dry. Salt and pepper all fillets except for the baby. Drizzle all 4 fillets with lemon juice.
Mix together the sour cream, pressed garlic, olive oil, parsley and nutmeg.
Cut the tomatoes into slices and remove the stalks.
Cut the puff pastry into 4 pieces, place the spinach leaves in the middle of each piece and place the fillets on top of the spinach - remember the baby piece! Depending on the size, add 2 - 3 tomato slices and 1 tablespoon of the sour cream mixture.
Fold the puff pastry upwards and place half a slice of cheese on the seam so that it does not burst.
Bake for 30 minutes.
There is also salad or baked vegetables.
Attention: Watch out for bones when dividing the baby portion!
Variation: use tomatoes, mozzarella and Italian herbs.
