01 - Place potatoes in a large pot and cover with cold salted water. Bring to a boil over high heat, then reduce to medium-low and simmer for 12–15 minutes until fork-tender. Drain through a colander and let cool slightly.
02 - In a large mixing bowl, whisk together Greek yogurt, Dijon mustard, vinegar, minced garlic, salt, and black pepper until smooth and fully combined.
03 - Add the warm, drained potatoes to the dressing. Gently fold to coat evenly, allowing the potatoes to absorb flavors while still warm.
04 - Fold in the diced celery, red onion, chopped dill, parsley, and chives. Mix gently to distribute ingredients without breaking up the potatoes.
05 - Taste the salad and adjust salt or pepper as needed. Refrigerate for at least 30 minutes to allow flavors to meld together before serving.
06 - Serve chilled or at room temperature. Garnish with additional fresh herbs if desired. This salad pairs well with grilled meats, fish, or veggie burgers.
