Preheat your oven to 400°F (200°C) 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.
Place the potato on the baking sheet and roast for 45 to 50 minutes, or until the center is tender when pierced with a knife.
While the potato is roasting, cook the bacon slice in a medium skillet over medium heat until crispy, then set aside on a paper towel to drain and chop into bits.
In the same skillet, add the ground turkey and season with garlic powder, sea salt, and black pepper, cooking until browned and no longer pink.
Once the potato is done, slice it in half lengthwise and carefully scoop out the flesh into a mixing bowl, leaving a thin layer of potato against the skin to maintain its shape.
Mash the potato flesh with the Greek yogurt and shredded cheddar cheese until well combined, then fold in the cooked ground turkey.
Spoon the mixture back into the potato skins, return them to the oven, and bake for an additional 5 to 10 minutes until the cheese is melted and bubbly.
Garnish with the chopped bacon and sliced green onions before serving warm.
