Preheat oven to 400°F and line a baking sheet with parchment paper.
Scrub the potato, prick with a fork, and bake for 45-50 minutes until tender.
In a skillet over medium heat, sauté the ground turkey in avocado oil until browned and cooked through.
Add tomato puree, chili powder, cumin, garlic powder, sea salt, and black pepper to the turkey; simmer for 5-7 minutes.
Slice the baked potato in half lengthwise and scoop out the center, leaving a 1/4-inch thick shell.
Place the skins back on the baking sheet and bake for 5 minutes to crisp the edges.
Spoon the turkey chili into the potato shells and top with shredded cheddar cheese.
Bake for another 3-5 minutes until the cheese is melted and bubbly.
Top with a dollop of Greek yogurt and a sprinkle of green onions before serving.
