Cut the fillets of fish into chunks measuring an inch each and place them in a resealable plastic bag.

Now in to a bowl place the onion, olive oil, cilantro, lemon juice, paprika, salt, pepper, chilli powder and minced garlic and stir well to ensure that the ingredients are mixed thoroughly together.

Now pour this mixture into the same bag as the fish.

Then close the bag and turn it over or shake until all pieces of fish have been coated in the marinade you have just made.

Once you have done this place the sealed bag in to a refrigerator and leave there for between 2 and 4 hours.

When it comes to cooking the fish remove from the bag discarding any marinade that remains and thread each chunk of fish on to the skewers you have been soaking in water.

Once you have thread each skewer with fish you should now lightly oil the grill on your preheated barbecue and place the skewers on to it.

You should be cooking the fish kebabs on a medium to high heat for between 8 and 10 minutes making sure that you turn them over occasionally to prevent them from burning.

As soon as they have cooked you should remove them from the barbecue and serve to your guests immediately.
