This vibrant coriander-lime chicken fajitas recipe is a nutritious take on a classic Mexican-style favourite. By marinating lean chicken breasts in a zesty blend of citrus, fresh herbs, and earthy cumin, the meat remains succulent while absorbing a deep, savoury flavour. The addition of charred poblano chillies and sweet yellow peppers provides an excellent crunch and a boost of vitamins, making this a colourful and balanced meal that is perfect for summer dining or a quick midweek feast.
