Doves Farm have a decent range of vegan offerings and the latest is Banana, Mango and Brazil nut cereal bars. Arriving in boxes of five, they offer a flavour not seen before in a cereal bar. The bars are pretty substantial at 40g each and will keep your hunger at bay. You're unlikely to get bored half way through like you can with some bland cereal bars though...these have a tasty tropical fruity flavour. They're also nice and moist, quite chewy and not too sweet.
