🧂 Ingredients

1 can of tuna (natural or in oil, drained)

3 eggs

½ onion, thinly sliced

1 teaspoon salt

1 pinch of ground pepper

½ teaspoon garlic powder

½ teaspoon dried oregano

100g grated mozzarella cheese

1 tablespoon vegetable or olive oil

🍳 Step-by-Step Preparation

1. Prepare the base mixture

In a bowl, place the drained tuna and add the eggs. Mix well until everything is combined.
Then season with salt, pepper, garlic powder, and dried oregano. Mix again to distribute the flavors evenly.

💡 Tip: If you want a fresh touch, add some chopped parsley or a squeeze of lemon.

2. Cook the onion

Heat the oil in a nonstick skillet and add the sliced ​​onion. Cook over medium heat until translucent and lightly browned.

3. Add the tuna and egg mixture

Pour the mixture over the onion and spread it with a spatula to form an even layer. Cook for 5 minutes over medium-low heat, until the base looks firm.

4. Add the finishing touch

Sprinkle the mozzarella cheese on top and a little more dried oregano. Cover the skillet and cook for about 3 more minutes, or until the cheese is completely melted and the surface is creamy and golden.

🍽️ Final result

You’ll have a juicy tortilla with a flavorful interior and an irresistible layer of melted cheese. It’s ideal for a light dinner, accompanied by a salad or a few slices of whole-wheat bread.

💡 Extra suggestion: You can replace the tuna with shredded chicken or add diced tomatoes and olives for a Mediterranean version.
