Stack sliced cheese on the non-buttered side of bread.
3 slices Havarti cheese
Add the second slice of bread to the top with the buttered side up.
Get a frying pan fitted with a lid hot over medium heat, then place the sandwich in the center of the pan. Cook for 2-3 minutes covered over medium heat, until the bread is golden brown.
Remove the lid, flip and replace the lid. Cook for another 2-3 minutes on the other side until both slices of bread are golden brown and the cheese is melted.
