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 olive oil and a pinch of sea salt.
Place the potato on the baking sheet and roast for 45 to 55 minutes, or until the skin is crisp and the inside is tender when pierced with a knife.
While the potato is roasting, heat a non-stick skillet over medium heat and add the ground turkey.
Cook the turkey until browned and cooked through, breaking it into small crumbles, and season with garlic powder, sea salt, and black pepper.
Steam the broccoli florets for 3 to 5 minutes until they are bright green and tender-crisp.
Once the potato is finished, slice it down the center and gently fluff the interior with a fork.
Stuff the potato with the seasoned ground turkey and steamed broccoli florets.
Top with the shredded cheddar cheese while the potato is hot so it melts slightly.
Finish with a dollop of plain Greek yogurt and a sprinkle of freshly sliced green onions before serving.
