Berry Chocolate (Antioxidant) Heaven

You can eat it if you're vegan, paleo, gluten free, dairy free, or just jones-ing for a good dessert and don't want any added sugar.

6 pints mixed fresh berries I used black-, blue- and strawberries — cut the latter in quarters
2 bars 72% or more dark chocolate chopped into small bits (ok, you can use cacao nibs if you're hard core paleo)
1 bunch fresh mint chopped

Seriously, that's it.
