These vibrant tequila-lime mahi mahi tacos offer a fresh, zesty take on a coastal Mexican classic. By marinating the firm white fish in a bright blend of citrus, garlic and tequila, the fillets develop a deep, savoury flavour that holds up beautifully against the heat of the grill. Each taco is balanced with a crisp red cabbage slaw and a silky lime crema, providing a satisfying contrast of textures that makes this dish a standout choice for a healthy, high-protein dinner.
Ideal for a quick weeknight meal or a casual weekend gathering, this recipe is both nutritious and incredibly simple to assemble. The combination of heart-healthy avocado and lean grilled fish makes for a light yet filling main course. Simply serve the warm tortillas in the middle of the table with plenty of extra lime wedges, allowing everyone to build their own perfect taco.
