Pre-heat the grill to hot.
Brush the slices of bread with the olive oil on both sides then toast on both sides for a couple of minutes until deep golden brown in colour. Remove and keep warm to one side.
Grill the rashers of bacon for 4-5 minutes, turning occasionally, until golden and crisp in appearance. Dice the bacon and toasted bread into evenly sized pieces.
