Place the peeled and quartered potatoes in a pot of salted water.
Bring the water to a boil and cook the potatoes for about 15 minutes until they are soft.
Drain the potatoes and mash them until smooth.
In a skillet, melt the butter over medium heat.
Add the chopped green onions and sauté for about one minute until they soften.
Pour in the milk and add salt and pepper.
Simmer on low heat for about 2 minutes, making sure the milk does not boil over.
Pour the green onion mixture into the mashed potatoes.
Mix everything together until creamy and well combined.
Serve warm with an extra pat of butter and a sprinkle of chopped green onions if you like.
