Lunch, the river, the walnuts...

Having exhausted the vegetarian options in the surrounding area, Penjamin suggested a picnic as a way of avoiding starvation. So a spot by the Dordogne, some cheese and bread, some wine, the October sunshine and we were as happy as a duck in a puddle.
Afterwards we stopped to buy walnuts from a farm on the side of the road. 7kgs later we left, pondering what to do with so many walnuts. I think I'll be looking up recipes for walnut breads and would warmly welcome suggestions from our loyal reader, assuming she's (a) not on holiday and (b) not allergic to walnuts.
