Preheat oven and pizza stone to 450 degrees.
-1 loaf ciabatta bread, split
-2 thin sliced sweet onions, carmelized (soften with 1T olive oil and add 1t of fresh ground black pepper, 1/2t kosher salt, 1T Lea & Perrins Worcestershire Sauce)
-About a 1 pound chunk of leftover pork loin roast sliced super thin (layer on top of onions in pan after adding sauce and heat through, flipping once to coat with yummy goodness)
-8 slices swiss cheese
Layer meat, onions and cheese on bread, close sandwich and wrap securely in foil (sprayed with cooking spray). Place on cookie sheet and top with hot pizza stone (yes, you can use a panini press but this works just as well and all the gooey goodness stays inside the foil). Bake for 10 minutes, unwrap, slice into six pieces and eat.
I suppose this is akin to a Cuban less the mustard, ham and pickles that I did have but decided to not use. Whatever you want to call it, it was DELICIOUS! (and there are no leftovers left over from the leftover, so I can't show you the final product)
