Spread tomato sauce on the tortilla.
Prepare the shrimp by cleaning them thoroughly and seasoning lightly.
Add toppings like shrimp, onion, bell pepper, etc., on top of the tortilla.
Sprinkle mozzarella cheese evenly.
Add olive oil to a pan and cook over low heat.
When the cheese melts and the bottom of the tortilla becomes crispy, it's ready to serve.
