Aubergine Lasagne by Jamie Oliver. It has the same vibe as a Greek moussaka, but uses pasta rather than potatoes in the layering, making it more of a lasagne bake. The fresh sheets you can buy in supermarkets are very good and well worth using.
Okay, so I was going to try to avoid using the word 'mushroomy' to describe this soup and subsequent pasta bake from the new Jamie Oliver's Comfort Food. But it's what they are, and frankly, that's a very good thing for them to be.
