I do a lot of cooking with mine in the Egg configuration, works amazing for things that you want to have a really hot sear and not cook for very long. I do all my steaks, Tris, boneless breasts, and venison that way. For fajitas it will work very nicely. NEver actually done any cooking with the middle section and no water pan though, may have to give that a whirl too if I have a bigger load of stuff to get cooked up.
