Notes & Inspiration
These miso tuna melts are a wonderful way to turn a humble tin of tuna into something deeply satisfying and nourishing. With around 45 g of protein per serve, they’re perfect for supporting energy, muscle repair and keeping you feeling full and satisfied.
White miso adds an incredible depth of savoury umami flavour to the tuna filling. It gently enhances the natural richness of the tuna and pairs perfectly with the creamy yoghurt and melting cheese.
A drizzle of crispy chilli oil or chilli crisp adds a lovely kick and a little crunch. It’s one of my favourite ways to finish this dish.
These melts are delicious on their own, or served with a simple green salad dressed with lemon and olive oil for a balanced and nourishing meal.
