Preheat your oven to 400°F (200°C).
Scrub the Russet potato thoroughly, prick 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, or until the skin is crisp and the inside is tender.
While the potato bakes, heat a non-stick skillet over medium-high heat and add the ground turkey.
Season the turkey with garlic powder, smoked paprika, the remaining sea salt, and black pepper, breaking it up with a spatula as it cooks.
Once the turkey is fully browned and cooked through, add the baby spinach to the skillet and sauté for 1-2 minutes until just wilted.
Remove the potato from the oven, slice it down the middle, and fluff the interior with a fork.
Stuff the potato with the turkey and spinach mixture.
Top with a dollop of non-fat Greek yogurt and garnish with freshly chopped chives before serving.
