In a small bowl, whisk together the egg whites, whole egg, sea salt, and black pepper until well combined.
Heat a medium non-stick skillet over medium heat and add the ground turkey, breaking it apart with a spatula until browned and cooked through.
Remove the turkey from the pan and set aside. In the same skillet, melt the ghee until shimmering.
Add the cherry tomatoes and sauté for 2 minutes until they begin to soften, then add the baby spinach and cook until just wilted.
Return the turkey to the pan and reduce the heat to medium-low.
Pour the egg mixture into the skillet. Using a silicone spatula, gently push the eggs from the edges toward the center to create soft curds.
When the eggs are nearly set but still slightly moist, fold in the fresh chives, parsley, and crumbled feta cheese.
Remove from heat immediately and serve while the eggs are velvety and hot.
