For the creamed spinach with boiled potatoes, fried egg and sausage bowl, boil the potatoes for about 20 minutes, peel them, cover them with the butter (so that it melts) and salt them.
Defrost the creamed spinach in a pot and warm it up on low heat. Peel the skin off the knackwurst and cut into slices up to 5 mm thick. Thicker slices will not curl as well when browned.
In a hot pan with oil, fry the sausage slices on one side until they bulge, remove and drain on paper towels.
Crack the eggs into the pan and fry them to make fried eggs. Season everything with salt and pepper.
