Preheat your oven to 425°F.
Wash the potato thoroughly. Pierce it with a fork a few times, then rub lightly with half a teaspoon of olive oil and sprinkle a pinch of salt over it. Bake for about 45-50 minutes until tender.
Once baked, allow the potato to cool slightly. Slice it in half lengthwise and gently scoop out most of the flesh, leaving a thin layer to keep the skins intact.
Place the potato skins back on a baking sheet, brush lightly with the remaining olive oil, and return to the oven for 10-12 minutes until the edges become crispy.
While the skins crisp, heat a non-stick skillet over medium heat. Add the lean ground turkey and chopped red onion. Sauté until the turkey is nearly cooked through, breaking it up with a spatula.
Stir in tomato paste, chili powder, garlic powder, salt, and pepper. Let the mixture simmer for 5 minutes until flavors meld and the turkey is fully cooked.
Spoon a generous portion of the turkey chili into each crispy potato skin.
Top each filled skin with sharp cheddar cheese. You may return them to the oven for 2-3 minutes if you prefer the cheese melted, or serve immediately for a mix of textures.
Serve warm and enjoy your balanced, protein-packed meal.
