Heat the oil in a large skillet over medium heat. Add the potatoes and sauté until softened, about 10 minutes, then add half the onion, garlic, ginger, and almonds. Sauté until the onion is translucent, 3 to 5 minutes. Add half the apples and butter and sauté until softened, another 3 minutes.
Transfer mixture to a medium sized serving bowl.
In a separate bowl mix mayonnaise and sour cream together, add remaining apple, remaining onion, lemon juice, Parmesan cheese, and capers. Toss well. Season with salt and pepper.
Serve on top of warm potato mixture. Garnish with the parsley and chives. Enjoy!
