Preheat your oven to 400°F and line a baking sheet with parchment paper.
Scrub the Russet potato thoroughly, pierce it several times with a fork, and bake for 45 to 50 minutes until the center is tender.
While the potato bakes, brown the ground turkey in a non-stick skillet over medium heat until no longer pink.
Stir in the black beans, tomato puree, chili powder, cumin, garlic powder, and half of the sea salt and black pepper.
Simmer the chili mixture for 5 to 7 minutes until the liquid has thickened, then set aside.
Once the potato is cool enough to handle, slice it in half lengthwise and scoop out the flesh, leaving a sturdy quarter-inch shell.
Brush the inside and outside of the potato skins with olive oil and season with the remaining salt and pepper.
Place the skins cut-side down on the baking sheet and roast for 5 minutes, then flip and roast for another 5 minutes until crispy.
Fill each crispy skin with the turkey chili mixture and sprinkle the shredded cheddar cheese evenly over the top.
Return to the oven for 2 to 3 minutes until the cheese is melted and bubbly.
Garnish with a dollop of Greek yogurt and freshly sliced green onions before serving.
