Green Bean and Tomato Salad with Buttermilk Dressing

This vibrant green bean and tomato salad is a wonderful celebration of seasonal produce. Combining crisp blanched beans with juicy heirloom tomatoes and sweet leeks, the dish offers a beautiful range of textures and colours. The creamy buttermilk dressing, infused with lemon and herbs, provides a tangy contrast to the fresh vegetables, making it an ideal light lunch or a sophisticated side dish for a summer barbecue.

The use of both cherry tomatoes and large heirloom varieties adds a lovely visual appeal to the plate. Serve it alongside crusty sourdough or grilled halloumi for a complete and wholesome meal that feels both indulgent and remarkably healthy.
