Nigel Slater's 'A Gratin of Spring Greens & Roasted Walnuts'.

I have lost the recipe for the above, it was in the April 2010 issue of Sainsbury's Magazine.

Can anyone help me out on this please and email the recipe to margsblogspot@blueyonder.co.uk - I would be really grateful, because it is to be a blog posting, and also my husband has requested I make this again!

Thanks.
