Greek Style Potato Salad

Heat a large pan of lightly salted water to a boil. Add the potatoes and boil just until fork tender. Drain the potatoes and cool completely under cold running water. Drain the potatoes well, peel and chop. Place the potatoes in a large bowl. Stir together the yogurt, mayonnaise, cucumbers, mint, dill, salt and pepper in a medium bowl. Pour the yogurt mixture over the potatoes and gently toss to combine. Cover and refrigerate the potato salad until ready to serve.
