Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Scrub the Russet potato clean, prick it several times with a fork, and rub the skin with avocado oil and a pinch of sea salt.
Bake the potato for 45 to 50 minutes, or until the skin is crisp and the inside is tender when pierced with a knife.
While the potato bakes, brown the ground turkey in a non-stick skillet over medium heat until fully cooked through.
Season the turkey with garlic powder, onion powder, the remaining sea salt, and black pepper.
Once the potato is done, slice it in half lengthwise and carefully scoop out most of the flesh into a mixing bowl, leaving a thin wall.
Mash the potato flesh with the non-fat Greek yogurt until smooth, then fold in the seasoned ground turkey.
Spoon the creamy mixture back into the potato skins and top each half with shredded cheddar cheese.
Return the boats to the oven for 3 to 5 minutes until the cheese is melted and bubbly.
Garnish with fresh green onions before serving warm.
