Peel and dice the potatoes. Cut the cauliflower into florets. Cook both together in 1/2 l vegetable stock for 10 minutes.
Dice the onion and sauté in the oil. Add the smoked pork cubes. I do this in a baking dish that can also be put on the stove.
Drain the vegetable stock and collect. Put the vegetables in the casserole dish with the Kasseler and mix a little.
Melt 2 tablespoons of butter in the stock pot and stir in 2 tablespoons of flour. Deglaze with the broth and stir in a nice sauce. Add the cream and the processed cheese and season with a little salt and pepper.
Sprinkle the cheese over the vegetables and pour the sauce over them. Bake for 20-25 minutes at 160 ° C hot air.
