In a medium bowl, combine the diced tomatoes, minced garlic, chopped basil, extra virgin olive oil, balsamic vinegar (if using), salt, and pepper.
Mix well and let the mixture sit for at least 15 minutes to allow the flavors to meld.
Preheat your oven to 400°F (200°C).
Arrange the sliced bread on a baking sheet.
Toast the bread slices in the preheated oven for about 5-7 minutes, or until they are golden brown and crispy.
Remove the toasted bread from the oven and immediately rub one side of each slice with the halved garlic clove for added flavor.
Spoon the tomato mixture generously onto each toasted bread slice.
Drizzle a little extra virgin olive oil over the top if desired.
Enjoy your meal!
