If you simply snack on nuts, it's easy to eat too many. A more sensible way to work them into your diet is to make some of the delicious Mediterranean and Mexican nut-based sauces and dips that I'll be offering here this week. They keep well in the refrigerator and can be used to accompany fish, vegetables or poultry. Many serve as a spread or dip with pita or bruschetta - or just eaten on their own.
