# How to Make It:
01 - Place the bread slices on a clean surface to prepare for assembly.
02 - Spread a thin, even layer of mayonnaise on one side of each bread slice.
03 - Optionally, spread a thin layer of Dijon mustard on the opposite side of two bread slices.
04 - Place two slices of cheese between two bread slices, ensuring the mayonnaise-coated sides face outward. Repeat for the second sandwich.
05 - Preheat a nonstick skillet over medium-low heat.
06 - Place sandwiches mayo-side down in the skillet and cook for 3 to 4 minutes until the bread is golden brown.
07 - Flip sandwiches and cook the opposite side for 3 to 4 minutes, pressing gently with a spatula until bread is golden and cheese melts.
08 - Remove sandwiches from skillet, let rest for 1 minute, slice, and serve immediately.
