2 cans French sliced green beans
1 can cream of mushroom soup
1/2 c. milk
1 can French fried onions (optional)

Mix drained green beans with soup and milk. Put into 2-quart baking dish. Put onions on top if you want them -- I don't bother. Bake at 350 degrees for 30 minutes. Or, use a microwave-safe dish. Cover and heat on HIGH for about 7 minutes. Put on onions and heat 1 more minute, uncovered.
