What is lurking inside children's school lunchboxes?

Apparently, parents are helping their youngsters go back to basics with jam sandwiches winning the contest against trendy foods such as salami or prawn rolls.

The good news for parents is that they are quick and easy to make and can be healthy too – with the wide range of no added sugar, or natural fruit spreads available today.

Time for a snack attack: get into school to see what lunches the children are taking in or if they're buying from the school canteen instead.
