Grab your bread slices and spread about a tablespoon of that vibrant green pesto on one side of each slice. Make sure to spread it evenly right to the edges - this layer of flavor is going to infuse every bite!

Take two of your pesto-covered slices and lay them pesto-side up. Pile a generous handful of shredded mozzarella (or lay down those creamy fresh mozzarella slices) on top. If you're feeling extra cheesy, sprinkle some grated Parmesan over the mozzarella for that sharp, nutty kick. Cap each sandwich with the remaining bread slices, making sure the pesto sides are facing down and touching the cheese.

Here's the secret to that irresistible golden crust: spread a thin layer of softened butter on the outside of each sandwich. Take your time here - you want an even coating that'll transform into that perfect crispy exterior.

Heat up a non-stick skillet or griddle over medium heat. Once it's hot, carefully place your sandwiches in the pan. Cook them for about 2-3 minutes on the first side, gently pressing down with a spatula. When the bottom is beautifully golden, flip and cook the other side for another 2-3 minutes until crispy and the cheese inside has melted into gooey perfection.

Transfer your masterpieces to a cutting board, slice them diagonally for that classic cafe look, and serve immediately while the cheese is still stretchy and the bread is crackling crisp.
