¼ cup (or more) finely chopped mixed fresh herbs, such as chives, thyme, parsley, basil and tarragon
Place the potatoes in a single layer in a medium saucepan with cold water to cover by 1 inch. Add a few pinches of salt. Bring to a boil, reduce the heat and simmer for about 30 minutes, until potatoes are just tender when pierced with a knife. Drain in a colander and let cool to room temperature.
Peel the potatoes and cut into ¾-inch pieces. Transfer to a bowl, toss with the oil and herbs and salt and pepper to taste. Serve at room temperature or cover and chill up to 1 day ahead and serve cold or at room temperature.
