Slice the baby pearl potatoes in half and cook in a pan of water until just soft. Drain well and allow to cool.
De-seed and dice the red pepper.
Transfer the cooled potatoes to a large bowl and add the red pepper, drained sweetcorn, thinly sliced spring onions, roughly chopped crispy bacon and chopped fresh chives.
Add the reduced fat mayonnaise and wholegrain mustard and mix well.
