Add the dates, almonds, pine nuts, milled flaxseeds and porridge oats into a food processor and mix until well incorporated.
To make the energy balls, roll about a tablespoon of the mix between your palms until you get a bite-size ball. Repeat the same process with the rest of the dough.
Put the ground pistachios onto a plate and coat each of the balls in them.
Notes
If you would rather make bars instead of balls, spread the mixture into a tray and cut it into squares.
Store them in the fridge where they will keep for a few days. You can also freeze them.
