Grilled Mahi-Mahi Tacos

These grilled mahi-mahi tacos are a vibrant, high-protein option for anyone seeking a fresh and light evening meal. The firm texture of the mahi-mahi makes it ideal for the grill, where it picks up a delicate charred flavour that contrasts beautifully with the zesty homemade salsa. By using a blend of smoked paprika, garlic, and dried herbs, the fish is infused with a deep, savoury warmth that brings a touch of coastal sunshine to your kitchen.

Perfect for a casual weekend lunch or a nutritious midweek dinner, this dish is as healthy as it is satisfying. The crisp, finely shredded cabbage adds a necessary crunch, while the smooth soured cream drizzle balances the subtle heat from the jalapeño and cayenne. Serve these colourful tacos with extra lime wedges on the side for a bright, citrusy finish that highlights the freshness of the seafood.
