Healthy-ish Chocolate Truffles

First and foremost these taste really good.  Its not one of those 'healthy alternatives' that people try and convince you taste just the same but actually taste like someone stirred in a little cow manure for authenticity.  I got the lads in the warehouse in work to taste one each and asked them all what they thought the secret ingredient was;  needless to say none of them guessed and many were appalled because they wouldn't have even tried an avocado in its normal state but they agreed that they were really nice except some of the lads didnt like the dark chocolate.  
It was a point of curiousity really that lead me to risk the chocolate on making truffles with a vegetable (well technically a fruit) even if it is one that I like.  These are incredibly easy to make, the hardest part mashing the avocodo down so that there are no lumps.  

Makes 12 Truffles

1 Small Ripe Avocado
140g Dark Chocolate
Cocoa for dusting

Method

1. Melt chocolate either in a bowl over a pot of simmering water or in a microwave for 30 seconds at a time stirring each time until its all melted.
2. Mash an avocado with a fork until its smooth like whipped cream.  Gradually add melted chocolate to the avocado.   Allow to cool and pop in the fridge for 20 mins.
3. Take teaspoons of the chilled chocolate mix and roll into a ball and toss in cocoa. Pop them back in the fridge for 5 mis to firm up or until ready to eat.
