In a medium mixing bowl, whisk together the whole eggs, liquid egg whites, sea salt, and black pepper until the mixture is uniform and slightly frothy.
Place the whole wheat bread slices in a toaster and toast until they reach your desired level of golden brown crispness.
Heat a non-stick skillet over medium-low heat and add the ghee, allowing it to melt and coat the bottom of the pan.
Add the fresh baby spinach to the skillet and sauté for approximately 1 minute, or until the leaves are just wilted.
Pour the egg mixture into the skillet over the spinach and let it sit undisturbed for about 30 seconds to set the bottom.
Using a silicone spatula, gently push the eggs from the edges toward the center, creating large, soft curds.
Continue cooking and folding gently for 2-3 minutes until the eggs are cooked through but still moist and creamy.
Transfer the scrambled eggs to a plate, place the toasted bread on the side, and garnish with freshly chopped chives before serving.
