Not on purpose.....However, many years ago..... when I was in North Africa, me and my acquaintances partaking of the local cuisine, ordered something from the menu with the label "crepes" (not being able to speak or read that Language) for breakfast. Something came on the plates that was wrapped in a thin pastry/pancake coating that looked liked an egg. When we cut into it with a fork, it was a whole egg, including the shell ---- well, we ate it, the shell was softened by whatever cooking process was used to make it. Maybe someone else here on BYC knows what it was we ate, I don't.
