Preheat oven to 180Â°C conventional (or 160Â°C fan-forced). Line a baking tray with baking paper. Remove crusts from bread. Cut each piece into 4 and spread each piece with tomato sauce. Top each piece with tomato and a square of cheese. Place onto a tray and into the oven until the cheese has melted (10-12 mins).Â Add a basil leaf to each slice. Cool and wrap in foil.
