Wash and peel the potatoes, then cut them vertically into thin fry slices.
Place the sliced potatoes in a bowl of cold water and let them sit for 30 minutes.
A few minutes before the potatoes are done sitting, preheat your oven to 425 degrees. Coat a large baking sheet with cooking spray.
Remove the potatoes from the water and blot them dry with paper towels or a dish towel. Transfer to a mixing bowl.
Drizzle in the avocado oil and sprinkle in the chives, sea salt and pepper. Toss to combine evenly, then transfer the potatoes to the baking sheet.
Bake for 15 minutes. Toss, then back another 10-15 minutes until the fries are at their desired crispiness.
(Optional) While the fries are baking, whip up the dipping sauce: Place the Greek yogurt in a small bowl. Add in the lime juice, garlic salt, and chives, and mix to combine well.
Once the fries are done cooking, remove from the oven and toss with the truffle oil, truffle salt and parmesan cheese.
Serve and enjoy!
