Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Scrub the Russet potato clean, pat dry, and prick several times with a fork. Rub the skin with olive oil and a pinch of sea salt.
Place the potato on the baking sheet and bake for 45-60 minutes, or until the skin is crisp and the inside is tender when pierced with a knife.
While the potato bakes, heat a non-stick skillet over medium-high heat. Add the ground turkey, garlic powder, onion powder, remaining sea salt, and black pepper.
Cook the turkey, breaking it up with a spatula, for 7-10 minutes until browned and cooked through.
Steam the broccoli florets in a steamer basket over boiling water for 4-5 minutes until bright green and tender-crisp.
Slice the baked potato down the center and fluff the inside with a fork.
Stuff the potato with the cooked ground turkey and steamed broccoli florets.
Top with the shredded cheddar cheese while the potato is still hot so it melts slightly.
Finish with a dollop of Greek yogurt and a sprinkle of sliced green onions before serving.
