# What You Need:
→ Vegetables
01 - 2 medium leeks, white and light green parts only, thinly sliced
02 - 1 tablespoon olive oil
03 - 1 tablespoon unsalted butter
04 - Pinch of salt
05 - Pinch of black pepper
→ Cheese
06 - 4 ounces Havarti cheese, sliced
→ Bread & Spreads
07 - 4 slices artisan or sourdough bread
08 - 2 tablespoons unsalted butter, softened
# How to Make It:
01 - Heat olive oil and 1 tablespoon butter in a skillet over medium heat. Add sliced leeks with salt and pepper. Cook, stirring occasionally, until leeks are soft and caramelized, approximately 12-15 minutes. Transfer to a plate.
02 - Lay out all bread slices. Spread one side of each slice evenly with softened butter.
03 - Place two slices butter-side down on a clean surface. Distribute caramelized leeks evenly over both slices. Layer Havarti cheese slices on top. Top with remaining bread slices, butter-side up.
04 - Heat a clean skillet or griddle over medium-low heat. Place sandwiches in the skillet and cook until bread is golden brown and cheese is melted, approximately 3-4 minutes per side. Press gently with a spatula to ensure even grilling and cheese contact.
05 - Remove sandwiches from heat. Slice each sandwich in half diagonally and serve immediately while warm.
