Roasted New Potato Salad With Olives

2 pounds small red new potatoes, rinsed, dried and halved
2 Tbsp. olive oil
1 1/4 tsp. herbes de Provence (mixed dried French herbs) or dried thyme leaves
Salt and freshly ground black pepper
1/2 cup pitted and coarsely chopped Kalamata olives
1/2 small red onion, cut into thin slivers
2 Tbsp. chopped fresh parsley
1 1/2 Tbsp. malt vinegar or rice wine vinegar
1 Tbsp. mayonnaise
1 small garlic clove, minced
3 Tbsp. extra-virgin olive oil

Toss potatoes in oil with herbs, a generous sprinkling of salt and a few grinds of pepper. Place potatoes, cut side down, in a single layer on a lipped cookie sheet. Set pan on lowest rack of cold oven; heat oven to 450 degrees.

Roast until cut side is golden brown and potatoes are tender, 20 to 25 minutes.

Transfer potatoes to a large bowl; add olives, onion and parsley.

Whisk vinegar, mayonnaise, garlic, a big pinch of salt and a couple of grinds of pepper in a 1-cup glass measuring cup. Slowly whisk in oil, first in droplets, then in a slow, steady stream. Pour dressing over warm salad; toss to coat. Serve at room temperature for best flavor.
