Preheat the oven to 400°F (200°C). Scrub the potato, pierce it several times with a fork, and bake for 45 to 50 minutes until the center is tender.
While the potato bakes, brown the ground turkey in a non-stick skillet over medium heat until fully cooked, seasoning it with half of the sea salt, black pepper, and garlic powder.
Cook the turkey bacon in a separate skillet until it reaches a crispy texture, then roughly chop it into small bits.
Once the potato is cool enough to handle, slice it in half lengthwise and carefully scoop out the flesh into a mixing bowl, leaving a thin shell of skin.
Mash the potato flesh with the Greek yogurt, cooked turkey, half of the shredded cheddar cheese, and the remaining seasonings until the mixture is well combined.
Spoon the potato and turkey mixture back into the potato skins, top with the remaining cheddar and the chopped turkey bacon, and bake for an additional 10 minutes until the cheese is bubbly.
Garnish the stuffed potatoes with fresh green onions and serve immediately while hot.
