Peel the potatoes and boil them whole in salted water. Drain them and let them cool.
Slice the onion, heat the oil in a skillet, add the onion, and begin to sauté. After a few minutes, crumble in the Smoked Wheat & Soy Salami. Stir thoroughly and add enough water to make it saucy.
Once ready, grease a baking sheet and layer half of the potatoes on it. Next, add the sausage, followed by the tofu slices sprinkled with black salt, and the vegan sour cream. Repeat this process until all the ingredients are used up.
Bake in a preheated oven at 180 degrees Celsius for about 20 minutes, covered with foil.
