# 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
# How to Make It:
01 - Lay out bread slices and spread a thin layer of softened 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 prepared slice with a remaining bread slice, butter side facing outward.
05 - Heat a non-stick skillet or grill pan over medium-low heat.
06 - Place sandwiches in the pan and cook for 3 to 4 minutes per side, pressing gently, until bread is golden brown and crisp and cheese is melted. Lower heat if bread browns too quickly before cheese melts.
07 - Remove from pan, let rest for 1 minute, then slice and serve immediately.
