This vibrant grilled chicken salad with romesco sauce is a testament to how simple, fresh ingredients can create a truly sophisticated meal. The dish centres on succulent, marinated chicken thighs served alongside a crisp medley of Little Gem lettuce, cucumber, and red onion. What elevates this recipe into something special is the homemade romesco—a velvety, smoky sauce crafted from charred red peppers and almond butter that provides a rich, savoury base without the need for heavy dressings.
Designed as a diabetes-friendly option, this salad is naturally low in carbohydrates while being packed with lean protein and heart-healthy fats. It is an excellent choice for a light summer dinner or a nutritious meal-prep lunch, as both the chicken and the romesco sauce can be prepared ahead of time. Serve it at room temperature for the best expression of flavour, perhaps finished with a light dusting of hot smoked paprika for an extra hint of Spanish-inspired warmth.
