While most of the ingredients for this recipe are common pantry staples, you may need to visit the supermarket for fresh fish fillets. Opt for any white fish such as cod, tilapia, or haddock.

Technique Tip for This Recipe
When grilling fish fillets, make sure to oil the grill grates lightly to prevent sticking. Additionally, use a fish spatula to carefully flip the fillets; this tool is designed to handle the delicate texture of fish without breaking it apart. For added flavor, consider marinating the fish in a mixture of olive oil, lemon juice, and herbs for about 30 minutes before grilling. This not only enhances the taste but also helps keep the fish moist during cooking.
