Preheat your oven to 400°F (200°C).
Scrub the Russet potato thoroughly, pierce it several times with a fork, and place it directly on the oven rack to bake for 45 to 60 minutes until the skin is crisp and the center is tender.
While the potato bakes, season the chicken breast with half of the sea salt and black pepper, then sear in a pan or roast until it reaches an internal temperature of 165°F.
Once the chicken is cooked, shred it into bite-sized pieces using two forks.
Cook the bacon slice in a small skillet over medium heat until crispy, then drain on a paper towel and crumble into small bits.
Steam the broccoli florets for 3 to 5 minutes until they are bright green and just tender.
Remove the baked potato from the oven and carefully slice it down the center lengthwise, fluffing the interior with a fork.
Stuff the potato with the steamed broccoli and shredded chicken, then sprinkle the sharp cheddar cheese over the top.
Place the potato back in the oven for 2 to 3 minutes, or until the cheese is completely melted.
Top the potato with a dollop of Greek yogurt, the crumbled bacon, and fresh chives before serving.
