Preheat oven to 450 F degrees.
In a small bowl, mix olive oil, garlic, salt and pepper.
Brush the oil mixture over each slice of bread, making sure you use all the garlic. Sprinkle mozzarella on each slice, then add a bit of basil to each slice.
Bake for about 5 to 10 minutes or until cheese has melted and it's slightly golden.
