I have a couple of whole Red Tilapia in the freezer. I love the whole grilled fish they do in Mexico. I have tried once years ago to grill whole fish but it stuck bad and fell apart. I am wanting to give this another shot. I seen one guy that put down sliced onions before laying the fish down which might work. Of course onions burnt to a crisp. I would like to use either my Char-Griller or Kettle. Both have SS grates. Any suggestions? I almost talked myself into just frying it but would like to try to grill one first.
