Preheat your oven to 425°F and line a small baking sheet with parchment paper.
Scrub the potato thoroughly and pierce it several times with a fork, then microwave for 5-7 minutes until tender.
Slice the potato in half lengthwise and carefully scoop out the flesh, leaving about a 1/4-inch thick shell.
Brush the inside and outside of the potato skins with olive oil and sprinkle with a pinch of sea salt.
Bake the skins for 10-12 minutes, flipping halfway through, until they are golden and crispy.
While the skins bake, brown the ground turkey in a non-stick skillet over medium-high heat until fully cooked.
Stir in the tomato puree, chili powder, cumin, garlic powder, and black pepper, simmering for 3 minutes until thickened.
Remove the skins from the oven and fill each shell generously with the turkey chili mixture.
Top with the shredded cheddar cheese and return to the oven for 3-5 minutes until the cheese is melted and bubbly.
Garnish with a dollop of Greek yogurt and freshly chopped green onions before serving.
