For traditional' Chicken Marsala you have to use chicken cutlets (breast), mushrooms, and sweet white 'Marsala' wine.
The chicken cutlets are coated in flour, and then briefly sautéed ~ browned on both sides in a combination of butter and olive oil. Then, you remove the chicken from the pan, and use the juices remaining (adding a bit of chicken stock from earlier this week) in the pan 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 champion mushrooms and fresh herbs.
As for the base, I think that a linguine pasta is perfect which should be cooking off to the side in a rolling boil of salted water. When the pasta is tender you are ready. If you want to slightly warm the chicken a bit before serving, then lay the cutlets back in the skillet with the sauce for a couple of minutes. Remove the cutlets and pour the sauce over the pasta and the chicken ... serve immediately.

*This dish can be made the brainy way too... using inexpensive semi sweet dry white wine; and, if you prefer not to use wine as children will sit to the table, then just don't use wine. To achieve a 'Marsala like wine' taste without using alcohol, add a good squeeze of fresh lemon/lime juice, 1/4 tsp of dry apple vinegar and 1/4 tsp of honey or organic cane sugar.
