Arrange an oven rack in the upper third of the oven, about 5-6 inches below the broiling element and heat the oven to 450 degrees F (230 degrees C).
Chop the tomato and place in a small bowl.
Stir in the Parmesan cheese, minced garlic, olive oil, balsamic vinegar, salt, and pepper.
Stir the basil into the mixture.
Brush one side of each slice of the bread with olive oil (a pastry brush helps with this) and place the olive oil side down on a baking sheet.
Place the baking sheet into the oven and toast for 5-6 minutes, until lightly browned around the edges.
Arrange the toasted bread on a plate, olive oil side facing up and top with the tomato mixture. When toasted, the olive oil helps to create a barrier keeping the bread from getting soggy from the chopped tomatoes.
Notes
Fresh Ingredients: For optimal flavor, always use the freshest ingredients available.
Toasting Alternatives: If you prefer, toast the bread slices dry until they're lightly browned on both sides. After toasting, rub a halved garlic clove over one side of each slice, then lightly brush with olive oil.
