Preheat your oven to 400°F and line a baking sheet with parchment paper.
Scrub the potato clean, pierce it several times with a fork, and bake for 45 to 50 minutes until the center is tender.
While the potato bakes, cook the turkey bacon in a skillet over medium heat until crispy, then finely chop.
Once the potato is cool enough to handle, slice it in half lengthwise and scoop the flesh into a mixing bowl, leaving a thin wall of potato in the skin.
Mash the potato flesh with the Greek yogurt, egg whites, sea salt, and black pepper until the texture is smooth and fluffy.
Fold in half of the cheddar cheese and half of the chopped bacon bits into the potato mixture.
Spoon the filling back into the potato skins, mounding it slightly, and sprinkle the remaining cheddar cheese on top.
Bake for an additional 10 to 15 minutes until the cheese is melted and bubbly.
Garnish with the remaining crispy bacon bits and fresh green onions before serving warm.
