Wash the potatoes thoroughly and cook in plenty of boiling water for 15-20 minutes. In the meantime peel onions and cut them into fine slices. Wash apples, peel them as desired and cut them into slices as well.
Wash the thyme. Heat 1 tablespoon of oil in a saucepan, lightly brown the onions. Add sauerkraut, apples, stock and apple juice and season with a little salt and pepper. Bring to the boil, place about 3 thyme stalks on the cabbage and braise covered for about 20 minutes.
Drain the potatoes, rinse them under cold water and remove the skin. Heat 3 tablespoons of oil in a coated pan. Fry the potatoes until golden brown. Season with salt and pepper. Roll up salmon ham and turkey breast slices.
Season the sauerkraut with salt and pepper and remove the thyme stalks. Arrange the apple sauerkraut with the roast potatoes on a large, deep plate. Place sliced rolls on top of the cabbage or arrange them separately and serve with the cabbage.
Serve sprinkled with remaining thyme and garnished.
