We used a combo of these type of disposable items last year.
For burgers & other meats (ie. bacon, etc)
For dogs & brauts
The smaller ones are easier to store and use.
I don't really have an idea on a pot/pan just something that will last us more than 1 season with all the abuse we do to it.
It it was the size/shape of the small item above great but I think those are more of a specialty item like this:
Figured a cast iron like this would take a beating forever
or even something like this for camping.
The cast iron dutch ovens are expensive. Bass Pro and Cabela's sell them.
