Start by adding the slices of bread to a large skillet over low heat greased with butter.
Add the beaten eggs seasoned with salt to taste and fry everything for 2 minutes.
After this time has passed, flip it and let it fry on the other side for another 5 minutes.
Next, cut the onion and the tomato into small cubes and finely chop green onions to taste.
Now, to assemble the dish, add the ketchup to the bread slices and spread it evenly.
Add the onion we chopped, the tomato, the green onions and finally, the mozzarella cheese cut into strips.
Cover the skillet and let everything fry for another 3 minutes or until the cheese is completely melted.
Serve.
