Preheat the oven to 400 degrees F.

Brush the baguette slices with olive oil and arrange on a baking sheet.

Toast 6 to 8 minutes, until golden and crisp.

Toss the diced tomatoes with garlic, basil, balsamic, remaining oil, salt, and pepper.

Let the tomato mixture sit 5 minutes to mingle.

Spoon the topping onto the toasts right before serving.
