Preheat your oven to 400°F and line a baking sheet with parchment paper.
Scrub the potatoes clean, prick them several times with a fork, and bake for 45-50 minutes until tender.
Once cool enough to handle, slice the potatoes in half lengthwise and scoop out the flesh, leaving about a quarter-inch of potato attached to the skin.
Place the skins back on the baking sheet, mist lightly with avocado oil spray, and bake for another 10-12 minutes until the edges are golden and crispy.
While the skins crisp up, brown the ground turkey in a non-stick skillet over medium heat until no longer pink.
Add the black beans, tomato paste, water, chili powder, cumin, garlic powder, salt, and pepper to the skillet.
Simmer the chili mixture for 5 minutes until the sauce has thickened and coated the turkey.
Divide the chili mixture evenly among the three potato skin halves and sprinkle with the shredded cheddar cheese.
Return to the oven for 3-5 minutes until the cheese is fully melted and bubbly.
Garnish each potato skin with a dollop of Greek yogurt and a sprinkle of sliced green onions before serving.
