Preheat your oven to 400°F (200°C).
Slice the baguette into 1/2-inch thick slices.
Arrange the slices on a baking sheet.
Brush each slice lightly with olive oil.
Toast the bread in the oven for about 5-7 minutes, until golden brown.
In a bowl, combine diced tomatoes, minced garlic, and chopped basil.
Drizzle olive oil over the tomato mixture, then season with salt and pepper.
Remove the toasted bread from the oven and let it cool slightly.
Top each slice with the tomato mixture.
Drizzle with balsamic glaze if desired and serve immediately.
