Preheat your oven to 400°F and scrub the potato clean, then pierce 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 fully cooked through.
Add the tomato puree, black beans, chili powder, cumin, garlic powder, sea salt, and black pepper to the skillet.
Simmer the turkey chili mixture for 5 to 8 minutes on low heat until the sauce has thickened significantly.
Remove the potato from the oven, slice it in half lengthwise, and scoop out the center flesh, leaving a 1/4-inch shell.
Brush the inside and outside of the potato skins with avocado oil and bake for 5 minutes per side until golden and crisp.
Spoon the turkey chili into the crispy skins, top with shredded cheddar cheese, and return to the oven for 2 to 3 minutes to melt.
Serve immediately topped with a dollop of Greek yogurt and a sprinkle of fresh green onions.
