Wash, clean and drain the lamb's lettuce. Rinse sauerkraut in a sieve briefly under running water and drain well. Coarsely grate the cheese. Slice the sausages lengthwise, but do not cut through, fill with cheese and wrap each with a slice of bacon.
Mix vinegar, salt, pepper and sugar, fold in oil. Heat 3 tablespoons of oil in a frying pan. Fry the sausages until crispy all around. Mix sour cream and remaining Gouda in a bowl, season with salt and pepper.
Cut open the hot dog buns, but do not cut through them. First cover with sauerkraut, then with sausages, ketchup and mustard, add cheese cream. Place on a baking tray lined with baking paper. Bake in a preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: see manufacturer) for approx. 4 minutes until the cheese has melted. Arrange the salad on a plate and sprinkle with Vínaigrette and place the hot dog on top.
