I will be cooking with my DO this weekend at a campsite that only has a grill (no firepit) and I'm not looking to carrying a whole DO table with me. The type of grill at this campsite has a non-removable grids so I need to put some kind of steel plate on top of the grids so I can cook up high and not on the floor. I keep reading that there are round steel pans to put the coals in and the DO in it, but I can't seem to find any. Or does someone have another suggestion of what I can use? I don't want to spend $20 on something like this (I did find one 18" steel pan for that much online) Thanks!
