LoL, I am tired of me splashing splattering grease all over the range as well. If you can do it on a stove burner, you can probably just as well do it on the extra grill burner just fine. That is one of the biggest benefits of a spare burner on the grill is to keep the mess outside.
I need to grill up some fish this summer. The wife claims she doesn't like Salmon. If it wasn't for the color, I could probably sneak it onto her plate though. Is there another fish that grills well but isn't too expensive. On second thought, maybe I just need to get out and catch a few.
