This versatile dish will impress! I recently served these as a side dish alongside herb and goat cheese stuffed chicken breasts at a formal sit down dinner, but they would be equally at home served family style, on a lunch or brunch buffet, or as a picnic or barbecue dish. They're awesome served warm, at room temp, or chilled.
Preheat oven to 400 degrees. Combine 1 1/2 Tbl olive oil, 1/2 tsp salt, 1/4 tsp pepper, garlic cloves, and potatoes in a roasting or jelly roll pan. Toss to coat well.
Bake at 400 degrees for 1 hr and 10 mins or until tender. Stir after 35 mins. Cool for 10 mins.
Squeeze the garlic cloves to extract pulp. Discard skins. Combine the garlic pulp, 1 1/2 tbl olive oil, 3/4 tsp salt, 1/4 tsp pepper, chives, vinegar and mustard in a large bowl. Whisk to mix well. Add potatoes to the bowl. Toss well to coat.
