Bring a large pot of water to a boil, add salt and cook the macaroni according to the packet's instructions. Drain well and let cool slightly while you prepare the rest.

In the meantime, halve the hard-boiled eggs and remove their yolk. Place the yolks in a salad bowl and mash them with a fork.

Add the mustard, mayonnaise, paprika, cayenne pepper, and some salt and pepper. Mix very well, then add the pasta to the bowl and mix well again to coat the macaroni with the dressing.

Heat a large pan and fry the bacon slices until crispy. Place them on kitchen paper to remove the excess fat. Chop the bacon into small pieces and add to the bowl.

Finely chop the egg whites, pickled cucumbers, onion and chives and add them to the salad as well. Mix well and add more salt and pepper to taste.
