Well I am sorry I am late. Perhaps you can use this for next time:
Put frozen chicken breasts (boneless skinless) in a 9x13 pan. Try to cram them on one side of the pan. (4-5 breasts) Add a large drained can of green beans to the other side of the pan. Put slices of peeled potatoes around the edges of the pan. (maybe 1/4" thick. Thicker and they'll not cook all the way. So when in doubt go thinner). Pour one stick of melted butter all over the top. Sprinkle the whole dish with one dry packet of Ranch salad dressing. Bake one hour. Yummy moist dish.
Added: Someone PMed me asking if it needs to be covered or not. I have made this dish once. I did not cover it until the second half of cooking probably. I flipped the potatoes a time or two so they'd get coated in butter and seasoning on both sides. So cover if you want, but it's not necessary unless your chicken isn't covered with butter in which case I'd likely rotate the chicken mid-way and/or cover. I made the mistake, when I made it, of sprinkling the green beans over the whole pan of chicken. I see why instructions say to separate the beans from the chicken, because when you go to serve it , you can't scoop out a spoonful of green beans b/c they're all over the pan. But hey - tasted good no matter how it's divied up. I plan to make this dish this week too. I got extra green beans and will cut my potatoes thinner. Other than that - I just keep an eye on it so it doesn't get dried out. But the butter helps keep it moist! Yumm.
