Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Scrub the Russet potato thoroughly, pierce it several times with a fork, and bake for 45-50 minutes until tender.
While the potato bakes, place a non-stick skillet over medium heat and add the ground turkey.
Cook the turkey, breaking it up with a spatula, until browned and no longer pink.
Stir in the chili powder, cumin, garlic powder, sea salt, black pepper, tomato sauce, and rinsed black beans.
Reduce heat and simmer the chili mixture for 5-7 minutes until the sauce has thickened and flavors are combined.
Once the potato is cool enough to handle, slice it in half lengthwise and scoop out the center flesh, leaving a 1/4-inch thick shell.
Brush the inside and outside of the potato skins with olive oil and return them to the oven for 5-8 minutes until the edges are crispy.
Divide the turkey chili mixture equally between the two potato skins and sprinkle with the shredded cheddar cheese.
Bake for another 3-5 minutes until the cheese is melted and bubbly.
Remove from the oven and top each skin with a dollop of Greek yogurt and a sprinkle of sliced green onions before serving.
