Close the sandwiches with the top halves of the rolls.
Place the sandwiches on the panini press or grill pan. Cook for about 5 minutes or until the bread is golden and the cheese is melted.
Serve warm.
Notes
Feel free to customize with your favorite fillings such as roasted vegetables, different cheeses, or pesto.
If you don't have a panini press, use a heavy skillet to press the sandwiches while grilling.
