In addition to the above, I also did a vidalia onion on the grill. After all, you have to have your veggies. I peeled it and cut an inch deep hole in the top. I filled the hole with bacon fat and chicken base, wrapped it in HD foil and put it on the grill for 30 minutes. Delicious!
I've got a Vidalia I picked up this past week for just that purpose. I use butter and beef soup base, but I like the idea of the bacon fat.
