Preheat oven to 350°F. Line a baking sheet with parchment paper or aluminum foil.

Use a serrated knife to cut the baguette at a slight angle into 1-inch slices. Arrange the baguette slices in a single layer on the baking sheet. Use a pastry brush to lightly brush the olive oil onto the bread slices. Set aside.

In a medium bowl, combine the chopped tomatoes, garlic, parsley, and white balsamic vinegar. Adjust seasoning to taste with salt and black pepper.

Using a slotted spoon, spoon tomato mixture evenly onto each slice of bread.

Bake for 5-7 minutes, until the bread is light golden brown. Transfer to a serving platter and serve warm.
