Preheat your oven to 400°F and lightly spray a baking sheet with olive oil.
Wash the potato thoroughly, then pierce it several times with a fork. Bake the potato for about 45 minutes or until tender.
Once baked, let the potato cool slightly. Slice it in half lengthwise and carefully scoop out most of the flesh, leaving a thin layer inside the skins.
Spray the insides of the potato skins with a little olive oil, season with salt and pepper, and return them to the oven for an additional 10 minutes to crisp up.
Meanwhile, in a nonstick skillet over medium heat, add the lean ground turkey. Season with chili powder, cumin, salt, and pepper. Cook until browned and crumbled.
Stir in the black beans and diced tomatoes, letting the mixture simmer for about 5 minutes until heated through.
Fill each crispy potato skin with the lean chili mixture, and top with shredded sharp cheddar cheese.
Place the loaded potato skins back in the oven for 3-4 minutes, just until the cheese melts.
Serve hot and enjoy your nutritious, protein-packed meal.
