Place two slices of bread in toaster and cook until golden.
Remove from toaster and immediately spread some butter on one side of each slice.
Place cheese on other side so that the butter is facing outwards and close the bread around the cheese to form a sandwich.
Place sandwich on a microwave safe plate and microwave for 15 seconds-30 seconds until cheese is melted.

Notes
To remove excess moisture from the sandwiches, you can wrap a paper towel around a sandwich while it's in the microwave. This will help to keep it somewhat crisp while cooking.You can use mayo instead of butter, if desired.NOTE: Microwaves vary in strength so if your cheese isn't fully melted after 15 seconds, continue cooking in 10 second intervals.
