Preheat your oven to 425° F or 170° C. And line a baking sheet with parchment paper.
Peel and cube the potatoes.
Put the cubes in a bowl. Add olive oil, salt, pepper and toss it well so it all gets coated.
Spread them out on the tray. Bake for about 30 minutes, flipping over halfway.
Meanwhile, mix the yogurt sauce. In a bowl, combine the yogurt, garlic, lemon juice, and olive oil. Mix well until smooth.
Set a pan over medium low heat and add the pine nuts. Toast, shaking the pan regularly, until you can smell them, about 1-2 minutes. Remove the nuts from the pan.
Remove the potatoes from the oven and pile them onto your plates.
Drizzle on the yogurt sauce and top with pine nuts.
Season with flake salt and ground pepper. Garnish with cilantro and a sprinkle of paprika.
