Place the sunflower seeds, almonds and Brazil nuts in a bowl with 3 cups of water and a tablespoon of lemon juice and soak for 4 hours. This will remove some of the phytic acid and also make the nuts easier to digest. Rinse and drain well.

Add the pre-soaked nuts with the rest of ingredients, except for chia seeds, to a food processor. Grind and process until thick batter is formed. Transfer to a bowl and mix in the chia seeds.

Roll the mixture into small balls using your hands (you might need to wet them slightly) and transfer to a sealed container. Refrigerate for a couple of hours to set. These will keep in the fridge for up to two weeks.
