Drain and rinse all the beans well. Add to a salad bowl.
Finely chop red onion, cucumber and sun dried tomatoes. Scoop up any excess oil from the sun dried tomatoes and add to the bowl.
Add all the dressing ingredients to a small bowl and whisk until combined. Pour over the salad and toss well with salad tongs until it is all coated.
Pop in the fridge or cover and leave to marinade for at least an hour. This will improve the flavour and allow the beans to soak up the juices!
