Bacon for sure
I'm all for what makes a pie taste yummy... not tradition. Don't get me wrong I like and GET the classics but with every bake I do some off the wall pies... some great... some not so much, but in my feeble mind you have to keep trying to know what is great.... not just what some Italian tradition tells me.
one of my favs though is roasted Hatch green chile, bacon, mozz with a sprinkle of fresh ground pepper. That is a match in heaven!
