A Menu Oddity

The first time I saw it I assumed it was a fluke. Chicken "Maryland,"  a dish I've now seen on several Argentine menus, combines the poultry with peppers, corn, ham, and banana sauce. As a native of "The Old Line State" I certainly saw lots of ham and peppers and corn growing up, and of course the Delmarva area is, locally famous for chickens. But, I never recall seeing a banana sauce, much less a banana growing in my home state.
I haven't had the nerve to order this particular Argentine invention yet.
