I guess it is a standard dish, I just didn't know what it was called. I'd had it once before and loved it but never knew what to call it. It is made for those who think green beans should be cast out of all cook books. It will change your mind. Well. it sure did change my mind.
These are plain old snap beans, not much flavor in them except just some sort of green taste. but they are thoroughly cooked with a couple of cans of mushroom soup and a small amount of milk and some french fried onions all mixed in together.
For me it is a taste sensation. For the first time in my life, green beans taste really good. and it all went perfectly well with the roast. and I didn't have to eat a horse while I waited.
Doggone it the pie disappeared before I was ready for desert but I had French vanilla ice cream and was a very satisfied customer.
