In May we explore the four cornerstone meals of the day — breakfast, lunch, dinner ... and snacks, of course! — and since last week was Breakfast Week, that means that this week is Lunch Week. What's happening in your lunch box lately? Need a little fresh inspiration? We have some fabulous tips and recipes coming up (one word: Ottolenghi), and we think you'll find some new things to crunch and munch. But do tell us: Is there something in particular you're craving for your lunch?
