Cut the salmon into bite-sized pieces and season with salt and pepper.

Dice the potato into 1cm cubes and soak in water to remove excess starch. Trim and cut green beans into 2cm pieces.

Boil water in a pot, add salt, and cook spaghetti according to package instructions.

Heat olive oil in a frying pan, cook salmon pieces over medium heat until the surface changes color, then remove from the pan.

Add diced potatoes to the boiling pasta water 3 minutes before the pasta is done, and green beans 1 minute before. Reserve 50cc of pasta water and drain the rest.
