Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Scrub the Russet potato thoroughly, pierce it several times with a fork, and rub the skin with half of the olive oil and a pinch of sea salt.
Place the potato on the baking sheet and bake for 45 to 60 minutes, or until the skin is crisp and the center is tender when pierced with a knife.
While the potato is roasting, heat the remaining olive oil in a non-stick skillet over medium heat.
Add the ground turkey to the skillet, breaking it into small crumbles with a spatula as it cooks.
Season the turkey with garlic powder, sea salt, and black pepper, and continue cooking until the meat is browned and cooked through.
Steam the broccoli florets in a steamer basket over boiling water for about 5 minutes until they are tender and vibrant green.
Once the potato is done, slice it open lengthwise and use a fork to gently fluff the interior.
Stuff the potato with the cooked ground turkey and steamed broccoli florets.
Top the potato with a dollop of nonfat Greek yogurt, a sprinkle of grated Parmesan cheese, and fresh chives before serving.
