01 - Preheat your oven to 375°F (190°C) to ensure proper baking temperature.
02 - Drizzle olive oil in a small ovenproof skillet or baking dish, coating the bottom evenly.
03 - Sauté onions and bell pepper over medium heat in the same skillet (if ovenproof) for 3–4 minutes until softened. Add garlic and cook for another 30 seconds until fragrant.
04 - Add tomatoes, oregano, and black pepper. Sauté for 2–3 minutes, allowing tomatoes to release their juices and create a light sauce.
05 - Remove from heat. Stir in feta cheese and optional Greek yogurt, spreading the mixture evenly across the skillet.
06 - Using a spoon, create 4 small wells in the vegetable and cheese mixture. Crack one egg into each well.
07 - Sprinkle lightly with salt, red pepper flakes (if using), and finish with a drizzle of olive oil over the top.
08 - Transfer the skillet or baking dish to the oven. Bake for 10–14 minutes, or until eggs are set to your desired doneness—whites should be opaque while yolks remain slightly runny for medium consistency.
09 - Remove from oven and garnish generously with fresh parsley. Serve immediately with crusty bread or warm pita for dipping.
