For the cauliflower you want to boil until soft like fork soft and hard boil your eggs.
I cooled the eggs and the cauliflower at the same time in ice water to help it cool. Apple cider vinegar helps it not have that cauliflower taste so I put in a splash in while cooling along with a sprinkle of salt.
Put together all the other ingredients in a bowl and mix than add the cauliflower and chopped eggs in and mix.
