For people who like to cook their fish just after catching them, Here is one way that I like to cook them.
1) With some foil, coat it with some olive oil
2) Slice some red potatoes, onions, carrots and some garlic in the foil.
3) Then put the fish into the foil and then seal it up.
4) put the foil on the BBQ for about 10 to 12 minutes. Flipping the foil about the halve way point 5 to 6 minutes point.
5) take the foil off the BBQ and open the foil. Add salt and pepper for taste.
