Preheat your oven to 400°F (200°C).
Heat the olive oil in a medium oven-safe skillet over medium-high heat.
Add the diced russet potato and yellow onion to the skillet, sautéing for 8-10 minutes until the potatoes are golden brown and tender.
Add the ground turkey to the skillet, breaking it apart with a wooden spoon, and cook until it is fully browned and no longer pink.
Stir in the fresh spinach and cook just until wilted, then season the entire mixture with sea salt, black pepper, and garlic powder.
In a small bowl, whisk the Greek yogurt with a tablespoon of water to reach a thick but pourable consistency, then spread it evenly over the turkey and potato hash.
Use the back of a spoon to create two small wells in the mixture and carefully crack one egg into each well.
Transfer the skillet to the oven and bake for 10-12 minutes, or until the egg whites are fully set but the yolks are still soft.
Remove from the oven and garnish with freshly chopped chives before serving hot.
