Blitz up the cashews, oats and dates in a food processor or grinder. I do this in batches as my grinder is smalll. You may need to stop grinding and stir it around a bit from time to time.Put the mixture into a bowl, add in the ginger and stir.Now roll into balls and roll in the sesame seeds (if wanted).Store in a tin, the fridge or freeze.Costing = £2.20 for 10 balls (5 portions for an adult)100g cashews £1.10100g dates 66p25g oats 27p1 tbsp sesame seeds 9p1 tsp ginger 8p
