Heat the olive oil in a large skillet over medium heat until shimmering.
Add the diced yellow onion and sliced red bell pepper to the skillet and sauté for 5 to 7 minutes until softened and slightly caramelized.
Stir in the minced garlic, ground cumin, smoked paprika, sea salt, and black pepper, cooking for 1 minute until highly fragrant.
Pour in the crushed tomatoes and stir to combine, then reduce heat and simmer for 5 minutes to allow the flavors to meld and the sauce to thicken.
Slowly whisk the liquid egg whites directly into the tomato sauce, stirring constantly until they are fully incorporated and the sauce becomes slightly opaque.
Use the back of a large spoon to create three small wells in the tomato mixture.
Carefully crack one whole egg into each well, then cover the skillet with a tight-fitting lid.
Cook for 5 to 8 minutes or until the egg whites are completely set but the yolks remain soft and runny.
Remove from heat and finish the dish with dollops of cool Greek yogurt and a sprinkle of chopped fresh parsley before serving.
