Place all ingredients apart from the chocolate in a food processor and process until everything comes together as a smooth dough.
Roll into balls and place on a tray. Pop into the freezer for around 15 minutes to harden up.
In the meantime, melt the chocolate in a Bain Marie and dip each truffle in. Place back on the tray and sprinkle with something sweet and green (use your imagination!). Put in the fridge until the chocolate has set.
