Arrange the slices of baguette or ciabatta on a baking sheet. Brush each piece lightly with olive oil on both sides.
Toast the bread for about 8-10 minutes, or until golden brown.
In a mixing bowl, combine the diced tomatoes, minced garlic, and chopped basil. Drizzle with 2 tablespoons of olive oil and season with salt and pepper to taste.
Once the bread is toasted, top each slice generously with the tomato and basil mixture.
Drizzle balsamic glaze over the top of each bruschetta if desired.
Arrange the bruschetta on a serving platter and enjoy while the bread is warm and crispy.
