Step 1

Heat a waffle iron.

Step 2

Butter both slices of bread on 1 side. Place 1 bread slice, butter side down, on the waffle iron. Layer on the cheese and top with the second slice of bread, butter side up.

Step 3

Close the waffle iron, but don't press it down, and let the sandwich cook for about 2 minutes, until the bread is golden brown and crisp at the edges. If you like your grilled cheese bordering on burnt, leave it in for up to 3 minutes. Sprinkle with salt, if desired.
