If the cabbage is very sour, rinse it, drain it, and set it aside. Sauté the onion until translucent, add the garlic, then add the spices after a few minutes and stir well.
Add the cabbage and mix well, then pour in enough water to cover it generously and cook, covered, until tender.
Cut the Smoked Seitan into large cubes and sauté in a little oil in a skillet. Once cooked, add it to the cabbage and cook for a few more minutes. Serve with fresh bread and vegan sour cream.
