Preheat your oven to 400°F and line a baking sheet with parchment paper.
Scrub the Russet potato clean, prick 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-high heat until no longer pink.
Stir in the tomato puree, chili powder, cumin, garlic powder, sea salt, and black pepper, then simmer on low for 5 minutes.
Once the potato is cool enough to handle, slice it in half lengthwise and scoop out the flesh, leaving about a quarter-inch shell.
Place the potato shells skin-side up on the baking sheet and bake for an additional 5 minutes to ensure they are extra crispy.
Flip the shells over, fill them generously with the turkey chili mixture, and sprinkle the shredded cheddar cheese on top.
Return the skins to the oven for 3 to 5 minutes until the cheese is completely melted and bubbly.
Garnish each loaded skin with a dollop of plain Greek yogurt and a sprinkle of fresh sliced green onions before serving.
