Chicken marsala is an Italian dish made from chicken, mushrooms, and Marsala Wine. The chicken is coated in flour, briefly sauteed, and then removed from the pan, which is then used to make a Marsala reduction sauce. The sauce is made by reducing the wine to nearly the consistency of a syrup while adding onions, as well as mushrooms and herbs. The sauce is then poured over the chicken, which has been kept in a warming oven, and served immediately.
FRA DIAVOLO refers to peppery dishes (mostly in the USA).
It means literally, "Brother Devil" and refers
to a Sicilian Robin Hood, Michele Pezza (1771-1806),
who disguised himself as a Franciscan friar and so was called 'Fra Diavolo'.
