Peel the potatoes, wash and cut into small pieces. Wash the onion, dry and finely chop. Drain the liquid from the canned food.
Boil the potatoes in salted water until tender. Using a masher, mash it into a puree. Mash the canned pink salmon with a fork.
In a deep bowl, mix the puree with mashed pink salmon, chopped onion, salt, pepper and mix well, then beat in the eggs and mix thoroughly again.
Heat a frying pan with vegetable oil, place the potato mixture in it, level it and fry for 20 minutes with the lid closed, then turn the pie over to the other side and fry for another 10 minutes. Serve the pie hot, cut into portions.
The dish can be served with sour cream, either on its own or as a savory pie for tea.
