Step 1

Finely chop the onions and garlic. A food chopper makes this quick and easy.

Step 2

Whisk together all the wet ingredients, lemon zest, onions, garlic, and pepper in a small bowl.

Step 3

Place the fish fillets in a shallow baking dish or gallon size zippered bag, and pour the marinade over the fish, turning the fillets a few times to ensure all are coated evenly.

Step 4

Place the fish in the fridge for about 30 minutes until ready to grill.

Step 5

Grill over medium heat for about 5 minutes per side. The flesh should flake easily when fully cooked.
