Preparing Tomato Basil Bruschetta is straightforward if you follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).

2. Prepare the Tomato Mixture: In a medium bowl, combine the diced tomatoes, chopped basil, and minced garlic.

3. Season: Drizzle the olive oil over the tomato mixture, and add balsamic vinegar if using. Season with salt and pepper to taste. Mix well and set aside to allow the flavors to meld.

4. Prepare the Bread: Arrange the sliced bread on a baking sheet. Brush both sides with olive oil for added flavor and crispiness.

5. Toast the Bread: Place the baking sheet in the preheated oven and toast the bread for about 5-10 minutes, or until golden brown. Keep an eye on it to prevent burning.

6. Assemble Bruschetta: Once the bread is toasted, remove it from the oven. Scoop a generous amount of the tomato mixture onto each piece of bread.

7. Serve Immediately: Enjoy the bruschetta right away while the bread is warm and crispy!

Each step in the process ensures that you create a delightful starter that is simple yet so rewarding.
