Combine the beans, onions, pickles and peppers together in a large bowl.

In a separate bowl mix the pickle juice and vinegar together along with a couple spoons of the beans. Smash the beans with a fork (don't worry about any onions and peppers that you may have scooped up). Add more pickle juice or water to adjust the volume as needed.

Pour the dressing over the salad and stir gently to combine.

Season to taste.

Place in the fridge for at least an hour before serving.
