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.
