Creamy Potato Salad

Hard-cook eggs (see Tip). Peel eggs and chop coarsely.

Meanwhile, place potatoes in a large saucepan, cover with lightly salted water and bring to a simmer over medium-high heat. Reduce heat to medium and cook, covered, until just tender, 15 to 20 minutes. Drain; let cool for about 10 minutes.

Meanwhile, whisk mayonnaise, yogurt, oil, anchovy paste and pepper in a small bowl until smooth.

Cut potatoes into cubes and place in a large bowl. Add vinegar and salt; toss gently to coat. Add bell pepper, onion, celery, parsley, gherkins, capers, chives, chopped eggs and the mayonnaise mixture; toss to coat well. Cover and refrigerate until chilled, at least 30 minutes.
