Preheat your oven to 400°F (200°C).
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 directly on the oven rack and bake for 45 to 60 minutes until the skin is crisp and the inside is tender.
While the potato bakes, place the ground turkey in a non-stick skillet over medium heat, breaking it apart with a spatula until fully browned and cooked through.
Stir the garlic powder, onion powder, sea salt, and black pepper into the turkey to season it evenly.
Steam the broccoli florets until they are tender-crisp and bright green, then roughly chop them into small pieces.
Once the potato is finished, slice it open lengthwise and fluff the interior with a fork.
Layer the seasoned ground turkey and chopped broccoli inside the potato.
Garnish with a dollop of Greek yogurt and a sprinkle of fresh sliced green onions before serving.
