Boil the chicken until cooked.
Boil the potatoes and carrots in a pot of salted water until cooked but still firm. Should take around 15-20 minutes.
Wait until the vegetables have cooled down a little bit and chop them into cubes. Take your time at this step, as it will take a while to get all ingredients chopped at the same sizes.
Drain the can of peas, and the pickles. Chop the pickles the same size as the vegetables. Chop the olives in halves.
Gently add all the ingredients together in a big bowl and mix with the mayo, the mustard and the salt and pepper. Be gentle, as you don’t want to crush the vegetables and end up with a mash instead of a salad
You can leave the salad in a bowl or transfer it onto a plate by pushing it down and then turning the bowl upside down. Decorate the salad with a layer of mayo and chopped olives, pickles, pickled red peppers, and even slices of boiled egg.
