Spangwich

Years ago (2004) there was an Adam Sandler/Tea Leoni film called "Spanglish."  If you didn't see it, don't rush out and get it.  A truly unremarkable film.  In fact, I don't think I even watched it until the end.  However, Adam Sandler (as a chef in the film) made a sandwich that not only stuck in my mind, but apparently many others due to the many different versions of this sandwich I found on-line (look at Pinterest, for example).

Therefore, I don't really have a true recipe here, but simply some possibilities to choose from.  The one non-negotiable ingredient, however, is the egg (and for me, the pesto).  And every recipe I looked at called for a runny egg (but if you, like my husband, would rather dance with a cobra than eat a runny egg, I won't tell if you use a hard-fried egg.....just don't call it a Spangwich!)
