Using a sharp knife, carefully slice your ciabatta rolls or focaccia in half horizontally. Slice the fresh mozzarella and ripe tomatoes into even 1/4-inch thick rounds. Pick the fresh basil leaves from their stems.

Lightly drizzle the cut sides of your bread with extra virgin olive oil. Sprinkle evenly with sea salt and freshly ground black pepper. Don't be shy, this seasoning layer really makes a difference!

On the bottom half of each piece of bread, layer the sliced fresh mozzarella, followed by the sliced tomatoes, and finally a generous handful of fresh basil leaves. Drizzle the balsamic glaze over the basil.

Place the top halves of the bread onto the assembled sandwiches. If you have a panini press, grill for 3-5 minutes until the cheese is melty and the bread is golden and crisp. If using a skillet, heat it over medium heat, lightly butter the outsides of the bread, and cook for 3-4 minutes per side, pressing down with a spatula, until golden brown.

Carefully remove the Caprese sandwiches from the grill or skillet. Slice in half if desired and serve immediately while warm. The melty cheese and warm tomatoes are pure bliss!
