First time I heard of this was on a Food Network show. It looked awesome to me, but I don't live in Chicago so I made my own version at home. So good! http://www.chicagopizzaandovengrinder.com/menu.htm
Chicago Style Pizza Pot Pie - place pizza topping and cheese in large ramekin, top with pizza crust and bake. Flip over to reveal a mini deep dish pizza! Easy to customize the ingredients! Fun twist to pizza night.
