For the dip, mix all ingredients in a medium-sized bowl. Chill until ready to serve.
Bring a large pot of water and 1 tablespoon of salt to a rapid boil. Add potatoes and cook for 20 minutes, until soft. Remove from water and allow them to dry completely in a colander.
Coat a large baking sheet with 1 tablespoon olive oil. Arrange potatoes on the baking sheet and use the bottom of a glass to gently press down on potatoes until they are 1/4-inch thick. Drizzle with remaining olive oil and season with salt and garlic. Bake for 25 minutes, until crispy.
Transfer to a plate and top with fresh herbs, and serve with chive dip.
