Preheat your oven to 375°F (190°C).
In a small oven-safe skillet, heat the extra virgin olive oil over medium heat and sauté the diced yellow onion until it becomes translucent.
Add the ground pork chorizo to the skillet, breaking it apart with a wooden spoon, and cook until browned and aromatic.
Stir in the fresh baby spinach and cook for 1 minute until just wilted.
In a separate small bowl, whisk together the non-fat plain Greek yogurt, sea salt, black pepper, and smoked paprika until the mixture is smooth.
Spread the seasoned yogurt mixture evenly over the chorizo and spinach in the skillet.
Use the back of a spoon to create three small wells in the mixture and carefully crack one egg into each well.
Sprinkle the crumbled feta cheese over the top of the dish.
Transfer the skillet to the oven and bake for 10 to 12 minutes, or until the egg whites are fully set but the yolks remain slightly runny.
Remove from the oven and serve immediately while hot.
