In a shallow dish you whisk together the garlic, white wine, soy sauce, lemon juice, olive oil, salt and pepper and savory seasoning.

Now place the swordfish steaks into the dish and turn them over so that they are coated in the marinade you have just made fully.

Then place in the refrigerator for one hour making sure that turn the steaks over frequently during this time.

After one hour remove the steaks from the refrigerator and turn on the barbecue.

Whilst the barbecue is heating up this will provide the steaks with sufficient time to reach room temperature and so will help to ensure that they then cook properly.

As soon as the barbecue has heated up it needs to be as hot as possible you lightly oil the grate and then place the swordfish steaks on to it.

Cook for 5 to 6 minutes on each side before then removing to a clean plate and garnish them with some freshly chopped parsley and wedges of lemon.
