Place shredded potatoes in a clean kitchen towel and squeeze out all excess moisture to ensure a crispy texture.
Heat avocado oil in a large non-stick skillet over medium-high heat.
Add ground turkey, onion, and bell pepper to the skillet, breaking up the meat with a spatula until browned and cooked through.
Season the mixture with sea salt, black pepper, and garlic powder.
Push the turkey mixture to the sides of the pan and add the shredded potatoes to the center, pressing them down to form a thin layer.
Cook the potatoes for 4-5 minutes without stirring until the bottom is golden brown, then flip and cook for another 3 minutes.
Whisk the whole egg and egg whites together in a small bowl, then pour the mixture over the turkey and potatoes.
Gently scramble everything together until the eggs are just set and fluffy.
Garnish with fresh chives and serve immediately.
