This vibrant prawn salad with cucumber and fennel is a wonderfully fresh choice for a light lunch or a sophisticated starter. The combination of succulent prawns and the crisp, aniseed notes of sliced fennel creates a sophisticated flavour profile that is naturally low in carbohydrates. Using lemon zest and fresh dill provides a bright, citrusy lift that perfectly complements the seafood without the need for heavy dressings.
