In a handheld chopper whizz the nuts (I toast them first in a dry frying pan until starting to brown just to increase the flavour - you don't need to do this) until they form a paste
Add the banana and egg and whizz into a smooth batter
Pre-heat a frying pan over a low heat and grease slightly if not non-stick
Place a tablespoonful of batter into the pan and repeat with spaces between each
Cook for 1-2 minutes on each side until golden. Watch them carefully since the sugar in the banana can make them burn easily!
Serve immediately with a little honey drizzled over if desired
