Peel the ripe plantain and slice it into 1/2-inch thick rounds on a bias.
Heat 0.75 teaspoon of ghee in a large non-stick skillet over medium heat.
Place the plantain slices in the skillet and cook for 3-4 minutes per side until they are deeply caramelized and tender.
Remove the plantains from the skillet and set them aside on a plate.
In a medium bowl, whisk together the whole eggs, egg whites, Greek yogurt, sea salt, and black pepper until the mixture is completely smooth.
Wipe the skillet clean and add the remaining 0.75 teaspoon of ghee over medium-low heat.
Add the spinach to the skillet and sauté for about 1 minute until just wilted.
Pour the egg mixture into the skillet with the spinach.
Using a silicone spatula, gently push the eggs from the edges toward the center, cooking low and slow until soft, creamy curds form.
Remove the eggs from the heat while they still look slightly moist to prevent overcooking.
Serve the creamy scrambled eggs immediately alongside the warm caramelized plantains.
