You'll need:
1 bag potatoes o'brien, thawed
8 oz cubed ham
Small container sour cream (or half a regular container)
1 can cream of chicken soup
2 cups cheese (when I'm not using up whatever leftover cheese I have, I but the mexican blend cause I like the flavor)

That's it. Mix it all together, place in slow cooker on low for about 6 hours. Be sure to let it cool some before you eat.
