Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Scrub the Russet potato clean, prick it several times with a fork, and rub the skin with olive oil and a pinch of the sea salt.
Place the potato on the baking sheet and roast for 45 to 60 minutes until the skin is crisp and the center 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, breaking it up with a spatula, until browned and no longer pink.
Season the turkey with the garlic powder, onion powder, remaining sea salt, and black pepper.
Add the fresh spinach to the skillet and toss for 1 to 2 minutes until just wilted, then remove the pan from the heat.
Once the potato is done, slice it down the center and fluff the inside flesh with a fork.
Stuff the potato cavity generously with the seasoned turkey and spinach mixture.
Top with a dollop of Greek yogurt and a sprinkle of freshly chopped chives before serving.
