For the first few months that Roo started school she had the exact same thing in the lunchbox, cheese and pickle sandwiches, a youghurt, and a piece of fruit. No matter how much I offered to make something else she always wanted cheese and pickle sandwiches. Now there is nothing wrong with a cheese and pickle sandwich but five days a week is pushing it.
Slowly she has increased her options and it varies between sandwiches, sandwich thins, sausage rolls and pasties. One of her favourite lunch box treats has to be my cheese, potato and pickle pasties. These as so simple to make and can be cut into almost any shape so can really cheer up a lunch box.
