# 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
# Step-by-step guide:
01 - Heat olive oil and 1 tablespoon butter in a skillet over medium heat. Add sliced leeks, a pinch of salt, and pepper. Cook, stirring occasionally, until leeks are soft and golden brown, approximately 12–15 minutes. Set aside.
02 - Lay out all bread slices. Spread one side of each slice with softened butter.
03 - Place two slices with buttered side down on a clean surface. Distribute caramelized leeks evenly on top. Layer with Havarti cheese slices. Top with remaining bread slices, buttered 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 for even browning.
05 - Slice sandwiches in half and serve warm.
