Step 1

Peel potatoes. Bring a large pot of water to a boil, add potatoes and cook for approx. 20 – 25 min., until tender. Peel onions and dice finely. Finely chop parsley and set aside.

Step 2

Heat a little oil in a small saucepan, add onion and sauté until translucent. Deglaze the onions with vinegar and vegetable broth, add bay leaf, and bring to a boil again. Add mustard, sweet mustard, and the remaining oil. Season with sugar, salt and pepper. In a small bowl, mix the starch with a little water. Add to the broth mixture and stir well.

Step 3

When the potatoes are cooked, drain them and rinse under cold water. Then cut into slices and add to a large bowl. Add the broth and let marinate for at least 20 min. Just before serving, finally stir in the parsley. Enjoy!
