Whilst waiting for the potatoes, cook the bacon medallions, then cut them into small pieces.
Drain the cooked potatoes and allow them to cool slightly.
Cut the potatoes in half and place them in a large bowl.
Add the chopped bacon, diced pepper, gherkins, pickled onions, spring onions, peas, hot sauce and juice from the gherkins. Mix well and season to taste.
Finally, stir in the chopped parsley and serve.
