Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Scrub the Russet potato thoroughly and prick the skin several times with a fork to allow steam to escape.
Rub the exterior of the potato with olive oil and sea salt, then place it on the baking sheet.
Bake the potato for 45 to 60 minutes, or until the skin is crisp and the inside is tender when pierced with a knife.
While the potato is roasting, brown the ground turkey in a non-stick skillet over medium-high heat until fully cooked.
Stir the black pepper, garlic powder, and smoked paprika into the turkey, then remove from heat.
Once the potato is done, slice it open lengthwise and gently fluff the interior flesh with a fork.
Stuff the seasoned ground turkey into the potato and top evenly with the shredded cheddar cheese.
Return the loaded potato to the oven for 2 to 3 minutes until the cheese is melted and bubbly.
Finish the dish with a dollop of plain Greek yogurt and a sprinkle of sliced green onions before serving.
