Mixed feelings about this one but I jazzed it up with sone chilli flakes sprinkled over at the end and added oregano plush fresh basil before I blended. Used cashew nuts in place of walnuts. 
Really enjoyed the end result with the additions. Tasty. 
I see some people have mentioned bland and  to be honest mine would have been too without the extras I've added. I think, for me at least, that's more down to the tasteless  supermarket peppers I'd bought. Not cheap ...just tasteless as so much veg is these days. When I tasted the raw chopped pepper it was just like water. Really annoying. Supermarkets...we need quality and not mass produced artificially grown tasteless produce!
