One at a time, cut the crusts off of each slice of bread, then use a rolling pin to flatten them.

Add a slice of cheese to each slice of bread, making sure you leave a small strip of bread showing at the end of the slice of bread to brush with butter.

Tightly but carefully roll up each slice of bread to the end, brush with butter, then roll shut and place seam-side-down.

Brush butter all over the roll .

Add roll ups to a dry pan seam-side-down over low-medium heat and fry until golden all over with the cheese starting to leak out. Use tongs to frequently turn them. You may need to do this in two batches depending on the size of your pan.
