Step 1: Prepare Your Ingredients
Begin by slicing your fresh mozzarella into ¼-inch thick rounds. If the mozzarella is very wet, gently pat it dry with paper towels to prevent your sandwich from becoming soggy. Slice the tomatoes to the same thickness for even layering. Wash and dry the fresh basil leaves, keeping them whole.

Step 2: Prepare the Bread
Slice your ciabatta loaf or rolls in half horizontally. If you prefer a crispier texture, you can lightly toast the bread cut-side up under the broiler for 2-3 minutes until just golden, or in a dry skillet for 2 minutes per side. This step is optional but helps prevent sogginess. If using, spread a thin layer of pesto on the bottom half of each piece of bread.

Step 3: Drizzle with Olive Oil
Drizzle 1-2 tablespoons of extra virgin olive oil over the cut sides of the bread. This adds flavor and creates a moisture barrier. Use a pastry brush or the back of a spoon to spread it evenly if desired.

Step 4: Layer the Mozzarella
Place the mozzarella slices on the bottom half of the bread in a single, slightly overlapping layer. Don’t pile them too high – you want a balanced ratio of ingredients in every bite.

Step 5: Add the Tomatoes
Layer the tomato slices over the mozzarella, arranging them in a single layer. Season the tomatoes generously with flaky sea salt and freshly cracked black pepper. This step is crucial – the salt brings out the tomatoes’ natural sweetness and enhances every other flavor.

Step 6: Add Fresh Basil
Arrange the fresh basil leaves over the tomatoes. You can keep them whole for visual appeal and maximum flavor, or tear them gently if you prefer a more evenly distributed basil taste.

Step 7: Drizzle with Balsamic
Drizzle the balsamic glaze (or balsamic vinegar) artistically over the basil and tomatoes. Don’t overdo it – you want just enough to add sweet-tart flavor without overwhelming the other ingredients or making the sandwich soggy. About 1 tablespoon per sandwich is perfect.

Step 8: Final Touch and Serve
Drizzle the remaining olive oil over the basil layer. Place the top half of the bread on each sandwich, pressing down very gently. If desired, slice each sandwich in half diagonally for easier eating and a beautiful presentation. Serve immediately while the bread is still crisp and the mozzarella is at room temperature.
