Subway yesterday launched a £2m multi-channel campaign for a new range of low-fat flatbreads

The nine-strong range of flatbread products contain less than 400 calories, less salt than its regular range of subs, and include one of your five-a-day, according to Subway.

They have been introduced as part of Subway’s work on reducing calories and salt in its products, as well as offering healthier options.

The new flatbreads are supported by charity Heart Research UK, and will be offered as an alternative to the range of low-fat subs and salads at the chain.
