I have tried a few green bean sides in the past but cannot find anything better than green bean casserole!
1 can cream of mushroom soup
2 cans cut green beans, drained
1 can fried onions
pepper to taste
Preheat oven to 350 degrees. Mix all ingredients, including half of the fried onions. Bake for 30 minutes. Top casserole with remaining onions and bake for 5 minutes.
