Preheat your oven to 400°F (200°C). Scrub the potato, pierce it with a fork, and bake for 45-50 minutes until tender.
While the potato bakes, finely chop the broccoli florets.
In a medium skillet over medium heat, add the olive oil and ground turkey. Cook until browned, breaking it into small crumbles.
Add the chopped broccoli to the skillet with the turkey and sauté for 3-4 minutes until the broccoli is bright green and slightly softened.
Once the potato is done, slice it in half lengthwise. Carefully scoop out the center flesh into a bowl, leaving a thin layer against the skin to create a boat.
Mash the potato flesh with the Greek yogurt, sea salt, black pepper, and garlic powder until smooth.
Fold the turkey and broccoli mixture into the mashed potato mixture until well combined.
Stuff the mixture back into the potato skins and top each half with shredded cheddar cheese.
Return the potatoes to the oven for 5-7 minutes, or until the cheese is melted and bubbly.
Garnish with sliced green onions and serve warm.
