Heat a large skillet over medium-high heat. Drop the butter on the skillet.

When the butter is melted and has a little bit of color, add the chicken breast halves.

Turn the heat to medium-low, cover and let simmer for some 10 minutes.

While the chicken is simmering, chop the green onions. Use both the green and the white part.

Turn over the chicken breast halves, cover and let simmer for another 10 minutes until the juices run clear. The total cooking time depends on the thickness of the meat.

Add the chopped green onions. Stir, and let the onions cook for 1-2 minutes.

Turn the heat off. Add the salt and sour cream. Mix well.

Cover and let stand on the stove top for 5 minutes. Mix well before serving.
