In a small bowl, whisk the Greek yogurt with a pinch of sea salt and half of the lemon juice until smooth, then spread it evenly onto the base of a serving plate.
Heat half of the olive oil in a non-stick skillet over medium heat and sauté the baby spinach with the remaining lemon juice until just wilted, then layer it over the yogurt base.
In a separate bowl, whisk together the whole eggs, liquid egg whites, garlic powder, and black pepper until the mixture is light and well combined.
Wipe the skillet clean and return to medium heat with the remaining olive oil.
Sprinkle the grated parmesan cheese in two even circles directly onto the hot skillet, allowing the cheese to melt and bubble for about 30 seconds until it begins to lace.
Carefully pour the egg mixture directly over the bubbling cheese circles and cook undisturbed until the edges are set and the bottom has formed a golden, crispy crust.
Gently fold the eggs over or flip them to finish cooking the top for another minute, then slide the parmesan-crusted eggs onto the bed of greens.
Garnish the dish with red pepper flakes and serve immediately while the cheese crust is at its peak crispness.
