Whilst chia seeds don't have a strong flavour, they add a really nice crunch to these bliss balls! Chia seeds are an unprocessed wholegrain food and were once a staple in the Mayan and Aztec diets. They can be absorbed by the body (unlike flaxseeds), and contain healthy omega-3 fatty acids, carbohydrates, protein, fibre, antioxidants and calcium - so they're really good for you!!
