Cucumber Potato Salad

Bring 1 in. water to a boil in a saucepan. Set whole potatoes in a steamer basket and steam in pan, covered, until tender, 15 to 20 minutes. Drain and allow to cool.

Whisk yogurt, mayonnaise, dill, vinegar, salt, and pepper in a small bowl to combine.

Quarter potatoes and put in a large bowl. Add onion, cucumber, and half the dressing; gently stir to coat. Add more dressing if you like, or save to use as a dip. Taste for seasoning since potatoes can soak up a lot of salt.

Make ahead: Chill potatoes and dressing separately and slice cucumber just before serving, then toss everything together.
