Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Scrub the Russet potato clean, pierce it several times with a fork, and rub the skin with olive oil and a pinch of sea salt.
Place the potato on the baking sheet and roast for 45 to 55 minutes, or until the skin is crisp and the inside is tender when pierced with a knife.
While the potato roasts, heat a non-stick skillet over medium-high heat and add the ground turkey, breaking it apart with a wooden spoon.
Season the turkey with garlic powder, the remaining sea salt, and black pepper, cooking until browned and no longer pink.
Steam the broccoli florets in a steamer basket or a small amount of water for 3 to 5 minutes until they are bright green and tender-crisp.
Once the potato is done, slice it down the center and gently fluff the interior with a fork.
Fold the sharp cheddar cheese into the hot potato flesh so it begins to melt.
Load the potato with the cooked ground turkey and steamed broccoli florets.
Finish by topping with a dollop of nonfat Greek yogurt and a sprinkle of freshly chopped chives.
