Preheat the oven to 400 degrees F. Cut bread into ¼-inch slices and place on a baking sheet. Lightly drizzle all the bread slices with the 1 tablespoon of olive oil. Bake for 10 minutes or until lightly toasted.
In a medium bowl, add diced tomatoes, chopped basil, garlic, balsamic vinegar, salt, pepper, and the remaining 1/2 Tablespoon of olive oil. Mix until combined. Cover and let sit in the fridge for 10 minutes so the flavors can blend.
Once the bread is toasted, spoon about 2 Tablespoons of the bruschetta mixture on each slice of bread. Drizzle a half teaspoon of balsamic glaze over each piece and a sprinkling of Parmesan cheese, if desired. Enjoy!
