Preheat your oven to 375°F (190°C) to ensure a perfectly even bake.
In a small mixing bowl, combine the ground turkey with smoked paprika, garlic powder, dried oregano, sea salt, and black pepper until well incorporated.
Heat the olive oil in a small oven-safe cast iron skillet over medium heat and sauté the diced yellow onion until it becomes translucent and fragrant.
Add the seasoned turkey chorizo to the skillet, using a wooden spoon to break the meat into small crumbles as it browns and cooks through.
Toss in the baby spinach and cook for 1-2 minutes until just wilted, then remove the skillet from the heat source.
Spoon the plain Greek yogurt over the turkey and spinach mixture, gently folding it in to create a rich and creamy texture.
Use the back of a spoon to create three small indentations in the mixture and carefully crack one egg into each well.
Sprinkle the crumbled feta cheese over the top and transfer the skillet to the oven, baking for 10-12 minutes until the whites are opaque but the yolks are still soft.
