Chicken Marsala Pizza

approximately 1 cup marsala sauce (I used a single package of Campbell's Skillet Sauces, Marsala)

sliced mushrooms

thinly sliced red onion

medium chicken breast (cooked and chopped (learn how to always have cooked chicken on hand))

large pizza crust ready for toppings (I cheated used two packages of a 'just add water' dough, but if you've got the time, here's my pizza dough recipe)

shredded mozzarella cheese (I like a lot of cheese, but do as you please)
