Precook the eggs: Eier für etwa 10 Minuten hart kochen. Abkühlen lassen and then pellen
Cook the eggs: Hard boil the eggs (about 10 minutes), then let them cool. Peel and roughly chop.
Cook the potatoes: Place whole potatoes in a large pot with generously salted cold water. Bring to a boil, reduce heat, and simmer until easily pierced with a knife (about 15 minutes, depending on size). Drain, cool slightly, then slice or quarter, and place in a large bowl.
Make the dressing: In a small bowl, whisk together the mayonnaise, olive oil, mustard, and pickle juice. Season with salt and pepper.
Dress the potatoes: While still warm, gently toss the potatoes with the dressing until evenly coated.
Add remaining ingredients: Fold in the eggs, pickles, radishes, parsley, and chives. Garnish with additional parsley and serve slightly warm, at room temperature, or chilled. Enjoy!
