Writing a book is a fulltime job. This I discovered last fall once I started to earnestly concentrate on completing my cookbook. What with my commitments in restaurant consulting and teaching, I have no time at all to prepare lunch. To utilize my time efficiently I buy commercial cold cuts, sliced cheeses and wheat bread to make sandwiches. But I yearn for the occasional comfort Chinese lunch that invariably sooths my anxiety about writing the book. So I need a new lunch plan.
