Chicken marsala is a classic Italian dish. The addition of mascarpone cheese and mustard creates another deeper, creamier and tangier layer of flavor. You need something to soak up the amazing sauce which is where the herbed cheese polenta comes in. Polenta is the Italian answer to mashed potatoes. Fresh Parmesan and parsley plus mandatory butter creates a cheesy and creamy side dish. The green beans are accompanied by tomatoes and basil to complete this easy weeknight dinner.
