Toast the sourdough bread in a toaster or oven until golden brown and crisp.
In a small bowl, combine the avocado, Greek yogurt, lemon juice, and half of the sea salt and black pepper.
Mash the avocado mixture with a fork until it reaches a smooth and creamy consistency.
In a separate medium bowl, whisk together the whole egg and the liquid egg whites until well combined.
Heat the avocado oil in a non-stick skillet over medium-low heat.
Pour the egg mixture into the skillet and cook, stirring frequently with a spatula, until the eggs are soft, fluffy, and just set.
Spread the creamy avocado mash evenly across the toasted sourdough slice.
Pile the scrambled eggs generously on top of the avocado layer.
Garnish the toast with hemp seeds, red pepper flakes, and the remaining sea salt and black pepper before serving.
