Green Bean Casserole

Since the left hand side of the recipe got chopped off, here it is again:
2-3 cans French cut green beans (drained)
1/2 stick butter or margarine
1/4 cup chopped onion
1 can cream of mushroom soup
1/2 roll Kraft garlic cheese
1 can Durkees french fried onion rings

Melt butter and saute onion until translucent. Add soup and garlic cheese, and heat until cheese is melted and blended. Pour over green beans and bake at 350 for about 25 minutes or until hot and bubbly.
