Prepare the bread: Preheat your oven to 400°F (200°C). Arrange the bread slices on a baking sheet and brush both sides lightly with olive oil. Toast in the oven for 5-7 minutes, flipping halfway through, until golden and crispy. You can also grill these on a grill pan for beautiful char marks!

Add the garlic: While the bread is still warm, rub each slice with the cut side of a garlic clove. This infuses the bread with subtle garlic flavor without overpowering the other ingredients.

Make the topping: In a medium bowl, combine the diced tomatoes, mozzarella, and basil. Drizzle with olive oil and balsamic vinegar, then season generously with salt and pepper. Toss gently to combine.

Let it marinate: Allow the mixture to sit for about 5 minutes. This lets the flavors meld together beautifully and the tomatoes release some of their delicious juices.

Assemble and serve: Spoon the tomato-mozzarella mixture generously onto each toasted bread slice. Drizzle with a bit more balsamic glaze if desired, and serve immediately while the bread is still crispy.
