Preheat your oven to 400°F (200°C).
Slice the baguette or ciabatta into 1/2-inch thick slices.
Arrange the slices on a baking sheet.
Brush both sides of the bread with olive oil.
Toast the bread in the oven for about 5 minutes until golden brown.
In a mixing bowl, combine diced tomatoes, minced garlic, and chopped basil.
Drizzle olive oil over the tomato mixture and season with salt and pepper.
Remove the toasted bread from the oven and let it cool slightly.
Spoon the tomato mixture generously over each slice of toasted bread.
Drizzle balsamic glaze on top before serving.
