Preheat oven to 200°C. Combine 2 tablespoons of the oil and the garlic in a bowl. Brush both sides of ciabatta with garlic oil and place on a baking tray. Cook in oven for 5 minutes or until golden. Remove from oven and transfer to a serving platter.
Spread ciabatta with pesto. Top with tomato and bocconcini. Sprinkle with basil leaves and drizzle with remaining oil. Season with salt and pepper and serve immediately.
