Soak the dates in a bowl of boiling hot water for approximately 5 minutes.
While waiting for the dates to soak, blend the walnuts, pecans, oats, cinnamon, nutmeg, salt and vanilla extract in the food processor until they're finely ground.
Next, add in the soaked dates and shredded carrots and process until well combined. This is where you'll need to play around a bit. With your hands, feel the consistency of the mixture. If it seems too wet and sticky, add a bit more of the oats. If it seems too dry, add a bit of water, one tablespoon at a time, until you reach the desired consistency. It should be sticky enough to roll into balls.
Next, roll each of the bites in some unsweetened coconut. Store in an air-tight container in the fridge for up to a week or in the freezer for up to three months.
