Dark Chocolate Pistachio Energy Balls

This is a spin off of the original energy ball recipe: Combine 1 cup dry oats, 1/2 cup natural peanut butter, 1/3 cup honey, 1/2 cup whole flaxseed, 1 tbsp cinnamon, 1 tsp vanilla, 3/4 cup chopped dark chocolate covered pistachios. Make sure that it is dark chocolate that doesn't contain milk. Roll the mixture into 1 inch balls and keep refrigerated.
