In a large mixing bowl, combine the whole eggs, liquid egg whites, Greek yogurt, vanilla extract, ground cinnamon, and sea salt.
Whisk the mixture vigorously for at least 60 seconds until the yogurt is fully incorporated and the eggs are frothy and light.
Heat a large non-stick skillet over medium-low heat and add the ghee, swirling to coat the bottom of the pan.
Pour the egg mixture into the skillet and let it sit undisturbed for 30 seconds to begin setting.
Using a silicone spatula, gently push the eggs from the edges toward the center, creating large, soft curds.
Continue cooking low and slow, stirring occasionally, until the eggs are just set but still look moist and glistening.
Remove the skillet from the heat immediately to prevent overcooking.
Transfer the scrambled eggs to a plate and top with the fresh mixed berries and hemp hearts.
Finish the dish with a drizzle of pure maple syrup and serve immediately while warm.
