Cooking in Yellowstone and Grand Teton NP

We will be staying within Grand Teton and Yellowstone National Parks for about four weeks this summer (Fishing Bridge in Yellowstone and Colter Bay Village in Grand Teton). Both state that cooking implements and food cannot be left outside. This makes sense to me, but seems to me it will create quite a few chores: haul everything out, fire things up, cook and eat, let everything cool, put everything away.

When we have camped with the travel trailer before, we left the grill, dutch ovens, and assorted other stuff outside.

Just wonder if others have been down this road and wonder what solutions they have come up with.

Thanks!
