hmm.. I think "JianBing" is the correct term, but the way you described it rather reminds me of the JianBing in TianJin (the port city very close to Beijing).. but they use this green bean paste and cook it from scratch on this slightly convex heated surface and then pour the egg on top, then flip and add the cilantro and stuff inside, usually there is another crispy wafer thing inside or those long fried Gouzi things. I dont really know the equivalent english terms unfortunately. I suggest visiting TianJin just for the streetcorner "JianBing Gouzi" I'm quite addicted but I wont be going to China for a rather long while.... :(

*edit- haha I just watched the video from the poster above me, and that's exactly what I was talking about, but the lady screwed up in the flipping bit lol
I miss Chinaaaa
