Coriander-Lime Chicken Fajitas with Grilled Onions

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.

As a high-protein option, these fajitas are ideal for those looking for a satisfying yet healthy dinner that doesn’t compromise on taste. The smoky charred red onions and peppers pair beautifully with the bright acidity of the lime juice. For a complete family-style spread, serve these directly from the grill with bowls of cooling soured cream, salsa, and plenty of creamy guacamole.
