Preheat your oven to 400°F and line a baking sheet with parchment paper.
Scrub the Russet potato and pierce it several times with a fork, then bake for 45-50 minutes until tender.
While the potato bakes, brown the ground turkey in a non-stick skillet over medium heat until fully cooked.
Stir in the black beans, tomato puree, chili powder, cumin, garlic powder, sea salt, and black pepper, simmering for 5 minutes.
Slice the baked potato in half lengthwise and scoop out the flesh, leaving a thin layer against the skin.
Place the skins back on the tray and bake for 5-7 minutes until the edges are golden and crisp.
Fill the potato skins with the turkey chili mixture and sprinkle the sharp cheddar cheese on top.
Return to the oven for 2-3 minutes until the cheese is melted and bubbly.
Garnish with a dollop of plain Greek yogurt and a sprinkle of sliced green onions before serving.
