Fluffy potatoes with sautéed cabbage form a delicious Colcannon recipe.
Place potatoes in a medium sauce pan and cover by 1" with water. Bring to a boil and boil for 15 minutes until tender. Drain, add 3 tbsp butter and milk and return potatoes to pot and mashed until desired consistency is reached.
Meanwhile, add 1 tbsp of butter to a skillet and add cabbage and white parts of the green onion and sauté until cabbage is just starting to soften.
Mix cabbage and potato together. Top with remaining butter and green onion.
