                Wash and scrub the potatoes. Place them in a large pot and cover with cold water. Add a pinch of salt and bring to a boil. Reduce heat and simmer for 15-20 minutes, or until tender. Drain and let cool slightly.

                Preheat the oven to 425°F (220°C). Arrange the potatoes on a parchment-lined baking sheet in a single layer. Gently smash each potato to about half an inch thick using a potato masher or the bottom of a glass.

                Drizzle the smashed potatoes with olive oil and season with garlic powder, salt, and pepper. Roast in the oven for 25-30 minutes, flipping halfway through, until golden brown and crispy.

                Toss the crispy potatoes gently with the dressing while they are still warm. Serve immediately or chill for at least 30 minutes to allow flavors to meld.
