Slice the crusts off of each slice of bread, then use a rolling pin to flatten.

Add a pinch of cheese to each slice, leaving a small strip at the end to brush with butter.

Tightly roll up each slice to the end, brush with butter, then roll shut and place seam-side-down. Brush all over with butter.

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.
