Alternate grilled cheese hack. Heat the skillet on medium till the skillet is hot. Really wait a couple minutes till it has come up to temperature. Melt a pat of butter on the skillet - don’t tear up you bread trying to spread butter on it. Cook the sandwich for one minute in the butter, move it to the side then melt another pat of butter in the empty space. Flip and cook the other side of the sandwich in the new butter. One min+ a little on this side.

Bonus look up inside out grilled cheese sandwiches and do them this way.
