Heat a little oil in a non-stick pan, then pour the egg mixture and cook over medium heat until it is completely thick, then turn the omelette with a spatula or with a lid and briefly cook the second side too. high flame.
Peel the potatoes and cut them into cubes.

When cooked, add the tuna and chopped parsley, then add salt.
