Preheat your oven to 400°F (200°C). Scrub the Russet potato and pierce it several times with a fork.
Bake the potato directly on the oven rack for 45-50 minutes until the skin is crisp and the inside is tender.
While the potato bakes, cook the turkey bacon in a skillet over medium heat until crispy, then chop into small bits.
Steam the broccoli florets until tender-crisp, then finely chop them.
In a small non-stick skillet, scramble the egg whites over low heat until just set, then set aside.
Once the potato is done, slice it in half lengthwise. Scoop out the flesh into a bowl, leaving a thin shell.
Mash the potato flesh with the Greek yogurt, garlic powder, sea salt, and black pepper until smooth.
Fold in the chopped broccoli, scrambled egg whites, half of the chopped bacon, and half of the cheddar cheese.
Spoon the mixture back into the potato shells and top with the remaining cheese and bacon bits.
Return the potatoes to the oven for 5-10 minutes until the cheese is bubbly and golden.
Garnish with fresh chives before serving.
