4 cups green cabbage, shredded
1 leek, pale-green and white parts only, chopped
1 cup milk
6 tablespoons butter, melted, divided
1/4 teaspoon nutmeg

- Spread mixture in an 8-inch square baking dish. Make a small well in the center, and place under the broiler until lightly browned on top, about 5 minutes. Remove from broiler.
