Melt butter, add salt, pepper and rosemary.

Marinate the salmon fillet and put in the aluminum foil and close tightly. Leave it for 1 hour.

Pour a little water on the small frying pan. Put salmon with aluminum foil (still closed tightly) into the pan. Cover and cook for about 15 - 20 minutes on low heat. If you notice there is no water add some. Sprinkle with lemon juice. (If you would like you can bake or fry salmon if you prefer).

Serve immediately with vegetables.

Pour water to the pan, add sliced carrots and frozen green beans. Simmer for about 30 minutes. Check if they are soft.
