This potato salad is equally delicious served in the cooler months as well as the summer. I add capers to this salad also, but that is optional. You can peel the potatoes if desired, I like to leave them on. Plan ahead the salad needs to chill for a minimum of 5 hours before serving. You can adjust the olive oil, white wine vinegar, and oregano to taste. Prep time does not include chilling times, cooking time is for boiling potatoes.
