Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
Scrub the Russet potato clean and slice it into thin, even fry-shaped wedges.
In a medium bowl, whisk the egg whites with sea salt, black pepper, garlic powder, and smoked paprika until slightly frothy.
Toss the potato wedges in the egg white mixture until thoroughly coated, then spread them in a single layer on the prepared baking sheet.
Bake for 25-30 minutes, flipping halfway through, until the fries are golden brown and crispy.
While the fries bake, cook the turkey bacon in a skillet over medium heat until crisp, then chop into small bits.
Remove the fries from the oven, bunch them together, and sprinkle evenly with the shredded sharp cheddar cheese and chopped turkey bacon.
Return to the oven for 2-3 minutes until the cheese is bubbly and melted.
Serve immediately topped with a dollop of non-fat Greek yogurt as a clean sour cream alternative and a sprinkle of fresh chives.
