# What You'll Need:
→ Bread
01 - 4 slices sourdough bread or artisan bread
→ Cheese
02 - 4.2 oz Gruyère cheese, grated or thinly sliced
→ Spreads & Oils
03 - 2 tablespoons unsalted butter, softened
04 - 1 to 2 teaspoons truffle oil, white or black
→ Seasoning
05 - Freshly ground black pepper to taste
06 - Pinch of sea salt, optional
# Directions:
01 - Lay out bread slices and spread a thin layer of butter on one side of each slice.
02 - Flip bread over and drizzle a few drops of truffle oil on the unbuttered side of two slices.
03 - Evenly distribute Gruyère cheese over the truffle oil-drizzled bread slices. Season lightly with black pepper and a pinch of salt if desired.
04 - Top each slice with the remaining bread slices, butter side facing out.
05 - Heat a non-stick skillet or grill pan over medium-low heat.
06 - Place the sandwiches in the pan and cook for 3 to 4 minutes per side, pressing gently, until the bread is golden brown and crisp and the cheese is melted. Lower the heat if the bread browns too quickly before the cheese melts.
07 - Remove from the pan, let rest 1 minute, then slice and serve immediately.
