Instructions

  1. Step 1: Place 1.5 lbs baby potatoes in a large pot and cover with cold water. Add 1 tsp salt and bring to a boil over high heat. Cook for 15-18 minutes until potatoes are fork-tender but not falling apart. Drain and let cool slightly.

  3. Step 3: Slice the warm potatoes into halves or quarters depending on size and add them to the dressing. Toss gently to coat the potatoes well.
  4. Step 4: Stir in 2 tbsp chopped fresh dill and 2 tbsp chopped fresh chives, mixing lightly. Let the salad rest at room temperature for 20 minutes to allow flavors to meld before serving.
