1. Prepare the Egg Mixture: In a bowl, beat the eggs with salt, black pepper, and oregano until well combined.
2. Cook the Eggs: Heat a non-stick pan over medium heat and pour in the egg mixture, ensuring it covers the entire pan. Let it cook for 1–2 minutes until it starts to set.
3. Add the Tortilla: Place the tortilla directly on top of the eggs while they are still slightly wet. Gently press it down to stick to the eggs. After 30 seconds, carefully flip the tortilla so the egg side is facing up.
4. Add the Toppings: Sprinkle the shredded mozzarella cheese over the surface, then add the sliced tomatoes and chopped green onions evenly across the tortilla.
5. Cook Until Golden and Crispy: Cover the pan with a lid and cook for 3–4 minutes until the cheese melts and the tortilla becomes crispy.
6. Serve & Enjoy: Remove from the pan, slice into wedges, and serve immediately. Enjoy it on its own or with your favorite dipping sauce.
