I have to say it sounds delightful.
Sweet 'chocolate flavoured' bread. 'Chocolate flavoured' sandwich spread and banana that has been 'messed about with' so it doesn't go brown.
All I can say to that thought is ............YUM
I don't think one will be finding it's way into my shopping trolley any time soon and if as you say they are a limited edition then I may just miss out all together.
Ahhh poor heart broken me. I will have to be strong and hope the feeling soon passes.
