Cod is a white fish with a mild flavor that is found in the coldest waters of the ocean. Cod is an excellent source of omega 3 fatty acids and vitamin B12. It is also a good low-calorie source of protein. Cod can be found at any grocery store or seafood dealer. Grilling cod is an easy and healthy way to prepare the fish. Serve grilled cod with healthy vegetables for a delicious meal.

Place the fish on a sheet of aluminum foil. Make sure that the foil sheet is large enough to completely wrap the fish.

Place small dots of butter on the fish fillets. Sprinkle garlic salt on the fish.

Cut a lemon into four pieces. Squeeze part of the lemon onto the fish. Slice the remaining lemon and place it on top of the fish.

Wrap the aluminum foil tightly around the fish. Place the fish on a grill that is set on low to medium heat.

Cook the fish for about 20 minutes. When cod is fully cooked it will flake easily with a fork. Be careful not to overcook.
