Preheat your oven to 400°F (200°C).
Scrub the potato and prick it with a fork, then bake for 45 to 50 minutes until the center is tender.
Slice the potato in half lengthwise and scoop out the flesh, leaving a quarter-inch layer against the skin.
Brush the skins with olive oil and sprinkle with sea salt and black pepper.
Return the skins to the oven and bake for 10 minutes until they become crispy and golden.
While the skins bake, brown the ground turkey in a skillet over medium heat until fully cooked.
Stir in the tomato paste, water, chili powder, cumin, and garlic powder, simmering for 5 minutes until thickened.
Spoon the turkey chili into the potato skins and top with the shredded cheddar cheese.
Broil for 2 to 3 minutes until the cheese is bubbly and melted.
Garnish with a dollop of Greek yogurt and sliced green onions before serving.
