I remember being a broody teenage who wanted nothing more than to take dinner to my room and forget that I was expected to interact with my family at dinnertime. All of that went out the window when I smelled chicken marsala cooking in the kitchen.
Most chicken marsala recipes call for mushrooms, but this one omits them simply because I did not like them as a kid. If you want to add them, use freshly-sliced 'shrooms and sauté them with the garlic in step 5.
