Tomato and Watermelon Salad

This vibrant tomato and watermelon salad is a celebration of summer flavours, offering a sophisticated balance of sweetness and acidity. The juicy heirloom tomatoes and crisp cucumber provide a wonderful contrast to the creamy Hass avocado, while the fresh watermelon adds a surprising, hydrating lift. It is a colourful, vegan-friendly dish that works beautifully as a light lunch or a striking side for an outdoor dinner party.

Drawing inspiration from Mediterranean flavours, this salad is elevated by the addition of toasted, ground coriander seeds and a rich, aged balsamic dressing. It is naturally healthy and incredibly quick to assemble, making it an ideal choice for warm afternoons. Serve it chilled alongside crusty sourdough or as a refreshing accompaniment to grilled vegetables to make the most of the seasonal produce.
