I spotted a recipe on Sunday for a 'modernised' green bean casserole. The original is green beans, can of mushroom soup poured over them, into oven for 30 mins, top with crispy onion rings. This is served with the Thanksgiving turkey alongside sweet potato pie topped with toasted marshmallows and other less weird things like stuffing and potatoes. How on earth can these have become traditional family favourites? Convince me someone.
