Mustard Scallion Potato Salad

Mustard Scallion Potato Salad

Ingredients:
potatoes, raw, skin
vinegar, cider
oil, olive, salad or cooking
mustard, prepared, yellow
onions, spring or scallions (includes tops and bulb), raw

Directions:
In a saucepan cover potatoes with salted cold water by 1 inch and simmer, covered, until just tender, about 15 minutes.
Drain potatoes well in a colander and, when just cool enough to handle, halve.
Transfer hot potatoes to a bowl and immediately toss with vinegar.
Add remaining ingredients and salt and pepper to taste and gently toss until combined well.
Serve potato salad warm or at room temperature.
