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 sea salt.
Place the potato on the baking sheet and roast for 45 to 55 minutes until the skin is crisp and the center is tender.
While the potato roasts, heat a non-stick skillet over medium-high heat and add the ground turkey.
Season the turkey with garlic powder and black pepper, breaking it up with a spatula until fully browned and cooked through.
Add the fresh spinach to the skillet during the last minute of cooking, stirring until just wilted.
Once the potato is finished, slice it down the center and fluff the inside with a fork.
Stuff the potato generously with the turkey and spinach mixture.
Top with a dollop of non-fat Greek yogurt and a sprinkle of freshly chopped chives before serving.
