Creating a Grilled Mozzarella Sandwich is straightforward and requires just a few simple steps:

1. Heat the Skillet: Place a non-stick skillet over medium heat.
2. Butter the Bread: Spread one tablespoon of unsalted butter on one side of both slices of bread.
3. Layer the Cheese: Place the mozzarella cheese slices on the unbuttered side of one slice of bread. Optionally, add fresh basil leaves for added flavor.
4. Season: Sprinkle salt and pepper over the cheese to enhance the taste.
5. Assemble the Sandwich: Place the other slice of bread on top with the buttered side facing up.
6. Grill: Carefully place the sandwich into the preheated skillet. Cook for about 3-4 minutes or until golden brown.
7. Flip: Using a spatula, gently flip the sandwich and grill the other side for another 3-4 minutes until the cheese is melted and the bread is golden brown.
8. Check the Cheese: Press down slightly on the sandwich with the spatula; you should feel the cheese getting gooey.
9. Remove from Heat: Once fully cooked, remove the sandwich from the skillet and let it cool for a minute.
10. Slice and Serve: Cut in half diagonally and serve immediately.
