It is a salad in its first life, but it is a large salad catering for 8 to 10 people as a side dish. So for a small family there will be leftovers ... when this happens, I place the leftovers the next night into a small baking dish, top the potatoes with either homemade breadcrumbs mixed with parmesan, or plain grated cheddar, and bake the dish for 25 to 30 minutes at 180 degrees (fan) until nice and golden on top. Delicious.
I have added chorizo to the finished dish purely because I like the contrast of the spicy sausage with the creamy potatoes ... but this is totally optional. I don't mix the chorizo through the salad, I simply place enough on top of the salad to make it appealing, and place the leftovers in a small serving bowl to be put onto the table for people to help themselves to. If you wish to keep this salad vegetarian but would still like to have a contrasting colour, then toasted pecan nuts work well too.
It is important to have the potatoes cut to no larger than 3cm. If you cut the potatoes larger then the cooking time will need to be longer, and you run the risk of the outside of the potato cooking quicker than the inside. If you stick to the size I suggest, you will find your potato stays intact without breaking down.
The salad can be completely prepared ahead of time and keeps really well for a couple of days in the fridge. If you need to make it ahead, then have it ready in a sealed container in the fridge (if you have it in a serving platter it can take up a lot of space in your fridge), and prior to serving place it into your desired platter, top with the chorizo (if using), spring onions and extra dill.
