Butter one side of each slice of bread.

Place two slices of cheese between two slices of bread, with the buttered sides facing out.

Heat a skillet over medium heat. Place the sandwich in the skillet and cook until the bread is golden brown and the cheese is melted, about 3-4 minutes per side.

Add shaved white truffles between the cheese slices before assembling the sandwich, reserving a few slices for garnish.

Once the sandwich is done, remove from the skillet and let it cool slightly. Slice in half and garnish with the reserved truffle slices before serving.
