Rinse and trim the green beans. Heat up a hearty dollop of butter in a frying pan large enough to fit both the fish and vegetables. Fry the green beans over medium heat for 3-4 minutes.

Season with salt and pepper to taste.

Move the beans over to one side of the frying pan.

If necessary, add more butter and fry the pieces of salmon for a couple of minutes on each side.

Stir the beans every now and then.

Lower the heat towards the end. Season the salmon and serve with the remaining butter.
