# What You'll Need:
→ Bread & Cheese
01 - 4 slices thick sourdough bread
02 - 2 slices sharp cheddar cheese
03 - 2 slices provolone cheese
04 - 1/2 cup shredded mozzarella cheese
→ Spreads & Fats
05 - 2 tbsp unsalted butter, softened
06 - 1 tbsp mayonnaise (optional, for extra crispiness)
# Directions:
01 - Lay out the sourdough slices. Spread butter evenly on one side of each slice. If using, spread a thin layer of mayonnaise on the opposite side for enhanced crispiness.
02 - Place two slices, buttered side down, on a clean surface. Layer each with 1 slice cheddar, 1 slice provolone, and half the shredded mozzarella. Top with remaining bread slices, buttered side up.
03 - Heat a large skillet or griddle over medium-low heat. Place sandwiches in the pan and cook for 3-5 minutes per side, pressing gently, until bread is golden brown and cheese is fully melted. Flip carefully to prevent spillage.
04 - Transfer to a cutting board and let rest for 1 minute. Cut diagonally and serve hot.
