1Preheat a skillet or a non-stick pan over medium heat.
Spread 1/2 tablespoon of butter on one side of each bread slice.
Place 4 slices of bread, buttered side down, onto the skillet.
Layer each slice with 1 slice of cheese and 2 slices of salami.
Top with the remaining bread slices, buttered side up.
Cook until the bread is golden brown and the cheese is melted, about 3-4 minutes per side.
Remove from the skillet, let cool slightly, and serve warm.
