Apparently the high nutritional value of avocados was well known by the Aztecs and the Incas. In the twenty-first century, it’s often what we put with avocado that makes our recipes somewhat less than healthy. This is a super-healthy avocado dip - with tofu, cider vinegar, yoghurt and spring onions – which loses none of the appeal of an avocado dip although it is packed with ingredients so healthy that even your cardiologist will be asking you for the recipe! Serve with crisp raw vegetables such as broccoli and cauliflower florets and sticks of celery, carrots and zucchini. Or, if you feel that the dip is healthy enough to make some small dietary sins permissible, serve with your favourite crackers. Adapted from the holistic.com website.
