The combination of ham and cheese with the sauce in this recipe is perfect!Maybe I am the only person left in the world who had never heard of these Open Faced Croque Monsieurs sandwiches before, but when I saw them pop up on the web one day I was very curious.  I thought to myself, “croque–WHAT?”  For those who have been living under a rock, like myself, a croque-monsieur is basically an upscale hot ham and cheese grilled sandwich.  The name is based on the verb croquer (“to crunch”) and the word monsieur (“mister”).  It’s roots are traced back to France and it is served in many cafes and restaurants there.  Go figure!

I made this for a quick and easy weeknight dinner but I was thinking this would also be perfect for a breakfast or brunch!  The ideal accompaniment to this dish would be a fresh green salad and a nice cold beverage.  Enjoy!
