In a medium mixing bowl, whisk together the 4 large eggs and liquid egg whites until the mixture is uniform and slightly frothy.
Stir in the sea salt, black pepper, and half of the chopped chives and parsley.
Place a non-stick skillet over medium-low heat and melt the ghee, ensuring the bottom of the pan is evenly coated.
Add the baby spinach to the skillet and cook for approximately 60 seconds until just wilted, then transfer the greens to a small plate.
Pour the egg mixture into the warm skillet and let it cook undisturbed for about 20 seconds.
Use a silicone spatula to gently sweep the eggs from the outer edges toward the center, creating large, soft ribbons.
Once the eggs are mostly set, sprinkle the crumbled feta cheese and the reserved wilted spinach over the top, folding gently to incorporate.
Remove the pan from the heat while the eggs still look slightly glossy to prevent overcooking, then garnish with the remaining fresh herbs.
