The concept for this sandwich was a mushroom, caramelized  onion, and cheddar sandwich at one of the local pubs – Kildares, I think.   Ruth made it up using mushrooms and a caramelized onion cheddar cheese.  On ficelle rolls.

I have made it a score of times, sometimes playing with it, and other times making it as it was originally intended.  It pretty much rocks the casbah no matter how it’s made.

The concept is quite simple – and pure brilliance.  Sauteed mushrooms, caramelized onion cheddar cheese melted into them after they’re browned really well, and then stuffed into a roll.

Did I say brilliance?!?

Two variations on a theme have been cooking the mushrooms with some ground beef, and adding in some slices of chicken breast as I did last night.

With sweet potato fries.

It really is a simple dish and the mushroom and cheese combination with the onions just makes everything right with the world.

If you don’t have a cheddar cheese that already has the caramelized onions in it, just cook up a handful and add it in with the ‘shrooms.

Rock your casbah.
