Salmon is a rich source of the omega-3 fatty acid DHA – an essential nutrient for good brain health and function. Plus it’s also high in protein, helping to support our muscles and protect bone health.

This gratin recipe uses sweet potato, but can easily be swapped out for butternut squash or potatoes. Experimenting with flavours can help to make this dish your own, so don’t be afraid to use what you have in the cupboard.
