Start by dicing fresh tomatoes and mixing them with finely diced red onion, basil, olive oil, salt, and pepper in a bowl. Press out any excess moisture.

Lightly brush one side of the ciabatta slices with extra virgin olive oil. Flip half of the slices over and layer them with fresh mozzarella and your prepared bruschetta mixture.

Carefully stack the oiled slice on top of the filling to prevent spills while grilling.

Preheat a griddle or frying pan over medium heat. Cook the sandwiches until golden brown, about 3-5 minutes.

Gently flip the sandwiches and rub them with a clove of fresh garlic as they grill.

Plate your sandwiches and drizzle with balsamic glaze before serving.
