Fruit and nut snack bar with citrus and chilli. Vegan Tuck Box supplied this bar as part of their sample box of treats, which we reviewed last week. It's a brand we haven't come across before or seen in the shops at all. These bars are not cereal bars as they have no grain ingredients, but they're a similar type of snack bar made from purely fruit and nuts. The texture of this style of bar is often dull, so can the spicy lime flavour perk it up?
