A nice and easy warm potato salad with a vinaigrette dressing.
Even though Linda recommends serving this salad warm, I think it is just as good when cooled to room temperature. As potatoes tend to soak up some or the flavour from the dressing, make sure you try the salad again before serving and adjusting the seasoning to taste.
I have used less olive oil (2 tbsp in total) to make this salad lighter.
