Easy Chicken Marsala in the Crockpot

"A Facebook challenge to cook something tonight in the Crockpot from the Crockpot FB page. Checked their recipies and tried their version of Chicken Marsala. Wanted to put it here for future reference and caloric/carb values. It is still in the crockpot with an hour to go and the house smells fantastic. I can't wait for my first bite. Serving over rice...haha, had some leftover from the other night...perfect way to use it up. I am low carbing and want to know how bad/good this is for my way of eating right now before I sink my teeth into it. Made a few adjustments to the original recipe....used unsalted butter (although it didn't specify what type of butter), garlic powder instead of garlic SALT (personally and seriously, I think the soup itself has enough salt)....Omitted salt (again) from original recipe. You can always add salt in to taste when you eat. Hope you make it and enjoy it. I will edit this recipe after I actually try it......1/2 hour to go now!!!! Edited on 3/13/11: Changed 1/2 cup butter (Yikes, one stick....now Paula Deen would love this!!) to 1/4 cup butter (1/2 stick unsalted butter). Although, you probably leave it off completely if it is a concern. Also changed the number of servings as well. Edited, yes again, on 4.8.11!! It was brought to my attention (thanks, you know who you are!!) that it maybe unclear on the amount of mushroom soup. Did a bit of investigation....2 smaller (10 3/4 oz.) cans of (Cambell's) mushroom soup is EXACTLY the 21 1/2 oz. needed in this recipe. If you plan to use a FAMILY-SIZED can it is 26 oz. that you would be putting in."
