I give this a 4 star as is, however, you can make it a 5 star and that is just what I did for Christmas with rave reviews. I used fresh whole green beans, fresh portabello mushrooms, and panko breadcrumbs for the topping. Fabulous! This is definitely elegant! No more kiddie green bean casserole for us!
