Efficient Use of the Egg?

Many of my cooks are high-heat, fast cooks, like burgers, steak, etc.

I light up the egg, wait about 1/2 hour for the temp to get up really high and the coals to burn off, then start cooking, which goes by pretty quick (often under 10 minutes).

Then I close up the vents.

The egg is so efficient, that the temp stays up usually well above 400 degress for a while.

I'm wondering if I can make use of this extended high temp time. I.e., shut down the vents on the egg, and stick something in it that will cook over the course of maybe 30 min- 1 hour while we are eating what I just grilled. It would have to be something somewhat low maintenance, as you don't want to keep going back out to look/take temps, etc., since you are eating your meal. Also, the temps will be slowly falling during this period, so you can't count on a sustained temp for too long.

One thought is maybe a small loaf of bread? Any other ideas? Perhaps something desserty? Cake?

Thanks!
