Green Bean Casserole

My kids LOVE green bean casserole and ask for it all the time. It's an easy recipe to teach kids to make.

2 cans green beans, drained
1 can Cream of Mushroom Soup
3/4 C. milk
dash pepper
1 small can onion rings

Combine soup, milk, pepper; add beans and 1/2 onion rings. Bake uncovered 30 min. at 350. Top with rest of onions and bake another 5 min.
