Peanua is a combination of peanut butter and a generic version of Nutella, a chocolate hazelnut spread. Peanut Butter and the chocolatey goodness of Nutella go great together on things like bread and bagels. The beauty of Peanua is that it guarantees that you will get the right proportion of peanut butter to Nutella in every bit.
I have been searching online to try to determine if you can purchase Peanua in the UK. From what I have found so far, it appears that it may only be sold in Lidls in the Czech Republic and Poland. It also does not appear to be listed by anyone on Ebay or Amazon.
