Easy Peasy Scalloped Potatoes

I made these for dinner one night last week and thought it was good enough to share. 

4-6 peeled and sliced potatoes
1 can of Cream of Mushroom Soup
1 onion { depending on how much you want, you could just use half }
1 can of milk


I sprayed the dish with Pam to help out with the sticking. Peel and slice potatoes. Dice onion. Layer potatoes and onion. Add Cream of Mushroom and mix in 1 can of Milk. Bake at 375 for about an hour. Cover for the last 30 minutes or so.
And of course I had to sprinkle a little cheese on top:)
