Preheat your oven to 400°F (200°C) and thoroughly scrub the Russet potato clean.
Pierce the potato several times with a fork to allow steam to escape, then rub the skin with half of the 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 when pierced with a knife.
While the potato is roasting, dice the chicken breast into bite-sized cubes and season evenly with the remaining sea salt, black pepper, garlic powder, and smoked paprika.
Heat the remaining olive oil in a non-stick skillet over medium-high heat and sauté the chicken for 6 to 8 minutes until golden brown and cooked through.
Once the potato is finished, slice it open lengthwise and use a fork to gently fluff the interior flesh.
Top the fluffed potato with the warm sautéed chicken, a dollop of non-fat Greek yogurt, and a garnish of freshly chopped chives.
