# Required ingredients:
→ 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, a pinch of salt, and pepper. Cook, stirring occasionally, until leeks are soft and caramelized, about 12 to 15 minutes. Set aside.
02 - Lay out the bread slices. Spread one side of each slice with softened butter.
03 - Place two slices, buttered side down, on a clean surface. Evenly distribute the caramelized leeks 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, about 3 to 4 minutes per side. Press gently with a spatula for even grilling.
05 - Slice sandwiches in half and serve warm.
