Preheat your oven to 400°F and scrub the potato clean before piercing it several times with a fork.
Bake the potato directly on the oven rack for 45 to 50 minutes until the center is tender when pierced.
While the potato bakes, brown the ground turkey in a non-stick skillet over medium heat until no pink remains.
Stir in the tomato puree, chili powder, cumin, half of the sea salt, and half of the black pepper, then simmer for 5 minutes.
Slice the baked potato in half lengthwise and scoop out the flesh, leaving a sturdy 1/4-inch thick shell.
Brush the inside and outside of the skins with olive oil and season with the remaining salt and pepper.
Place the skins cut-side down on a baking sheet and roast for 5 minutes, then flip and roast for another 5 minutes until crispy.
Fill each skin with the turkey chili, top with shredded cheddar, and bake for 3 minutes until the cheese is bubbly.
Serve topped with a dollop of Greek yogurt and a sprinkle of freshly sliced green onions.
