At the risk of being banned from the forum can I suggest a "fauxtato salad"
Steam a head of cauliflower so it is still quite firm but cooked, then put into cold water to chill. While it is chilling, in a bowl, combine a dollop of Dijon mustard, 5 or 6 dollops of mayonnaise, a finely chopped red onion and 3-4 large dill pickles, also finely chopped, and then refrigerate the mix.
Boil 3 or 4 large eggs until hard boiled and grill 3 or 4 rashers of bacon until crispy before dicing into small pieces (I cheat and just crisp up half a packet of lardons)
Discard the cauliflower stalks and hand crumble the head into small pieces (think big breadcrumbs) and then fold into the mayo mix along with the bacon. Quarter up the eggs, gently combine and back in the fridge for a bit. Really tasty and low carb
