Instructions
In a large pot, bring salted water to a boil. Add the cubed potatoes and cook until tender, about 15-20 minutes. Drain and set aside.
In a large skillet, melt 2 tablespoons of butter over medium heat. Add the chopped onions and sauté until golden, about 5 minutes. Add the shredded cabbage and chopped kale, cooking for an additional 5-7 minutes until the greens are tender.
In a large bowl, mash the drained potatoes with the remaining 2 tablespoons of butter until smooth. Stir in the sautéed onion, cabbage, and kale mixture. Add the grated cheddar cheese, and season with salt, pepper, and a pinch of nutmeg if desired. Mix until well combined.
Preheat your oven to 375°F (190°C). Transfer the Rumbledethumps mixture to a greased baking dish. Sprinkle with additional grated cheddar cheese on top for a cheesy crust.
Bake in the preheated oven for 25-30 minutes or until the top is golden and bubbly.
Remove from the oven and let it cool for a few minutes. Garnish with freshly chopped chives before serving.
