# 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 - 1-2 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 slices and drizzle truffle oil on the unbuttered side of two slices. Distribute Gruyère cheese evenly over the oiled bread, then season lightly with black pepper and salt if desired.
03 - Top each cheese-laden bread slice with a remaining bread slice, positioning the buttered side facing outward.
04 - Heat a non-stick skillet or grill pan over medium-low heat until evenly warmed.
05 - Place sandwiches in the pan and cook for 3-4 minutes per side, pressing gently until bread is golden brown and crisp with melted cheese inside. Lower heat if bread browns too quickly before cheese melts completely.
06 - Remove sandwiches from pan and let rest for 1 minute. Slice diagonally and serve immediately.
