Let’s prepare the vinaigrette dressing. This is a classic French salad dressing. You can mix the sauce in a jar with a tight-fitting lid or in a small bowl. This amount of dressing is enough for two servings of salad. In a bowl, combine the mustard powder, salt, Herbes de Provence, and a pinch of pepper. Squeeze in the lemon juice and add a quality wine or apple cider vinegar. Mix well, then pour in the extra virgin olive oil. Whisk everything vigorously again until the salt has completely dissolved. The vinaigrette dressing is ready, it’s that simple!

Dice the potatoes boiled in their jackets into large cubes and place them in a bowl. To quickly peel boiled potatoes, drain the hot water and immediately pour cold water over them, letting them sit for 1-2 minutes. After this temperature shock, the skin will peel off effortlessly.

Wipe the fresh champignon mushrooms with a damp cloth. Slice the mushrooms coarsely. Sauté for 5 minutes in a mix of butter and vegetable oil. Don’t overcrowd the pan with mushrooms; they will cool down the oil and the pan, release a lot of moisture, and end up stewing instead of frying. Cook the mushrooms in small batches.

Let the sautéed mushrooms cool, then add them to the salad.

Thoroughly wash the green onions, pat them dry with a paper towel, and chop finely. Add the chopped onions to the other ingredients. If you’re making the salad ahead of time, add the onions just before serving.
