I really dislike pastry but love quiche and this is a tasty alternative to the traditional version. Also my mother was Irish and she said I was true to my heritage inventing a new way to use potatoes.
Don't be stingy on the ingredients. Changing some of the potatoes for orange sweet potatoes is also tasty and slightly better for diabetics. Salmon and leek also works instead of spinach and ham. Heats up really well for lunch the next day. I usually make 4 at a time and my children's friends all turn up when they know I am making potato quiche. All my children cook it too. Can be served on its own or with salad
