This is a very traditional Dutch dish, which I have learned to make since marrying a boy from Holland. It was always part of the celebrations at 'Carnaval', the party before Lent begins - the Dutch version of 'Mardi Gras'.
For 4 servings.
What you need: 2 large bunches of kale; 1.5 kilos of potatoes; milk and butter, salt, and pepper for potatoes; 4 farmers sausages, the individual size; or 1 kilo of a sausage of your choice; 2 cups of gravy.
What you do: Separate kale leaves and wash them. Cut off the thick centre spine. Prepare and cook potatoes for mashing. In a very large kettle, cover the kale leaves with water, and bring to a boil. Simmer for about 10 minutes. Heat sausage in a pan of water, a frying pan, or on a grill. Mash potatoes, and add salt pepper, butter, and milk as desired. Drain the kale. Chop the leaves into small pieces. stir into the mashed potatoes.
Serve sausage and potato mixture with gravy on top.
