I got this recipe off a Paula Deen's cooking show. I didn't like the way the chicken cooked in the mixture so I either cook the chicken separately or I use the chicken already grilled at the store.Then I add it to the mixture the last 4 minutes of cooking. Try it either way and it is really good.
Melt butter in skillet, add onions and mushrooms, Cook for 10 minutes. Season chicken and fry in mixture. This is where I change the recipe, I cook the chicken separately or use precooked grilled chicken and add to mixture the last 4 minutes of cooking. Then add mozzerella cheese and let melt. Enjoy.
