This is a zingy potato salad, ideal for accompanying fried fish or lamb shish kebabs. Goes well with cold lager or cider. The colours are great and liven up the usual dullness of a standard potato salad, not to mention the spicy taste.
This is a gorgeous way to eat potatoes in the summer. Also you can add a bit more chilli to make a fiery version which goes well with red meats in the winter.
I always use two small onions instead of one large one, I find the smaller ones more juicy.
