Green beans are perfectly good on their own, but roasted onions and a sweet-tart vinegar sauce make them much more interesting. Add the optional dried cranberries if you want another little bit of color and sweetness.
The onions take most of the cooking time. While they roast, reduce the broth with vinegar and sugar, then steam the beans just until they are as tender as you like them. Pile the onions and sauce over the beans at the end.
This recipe serves ten, so it is useful for a larger family meal or a table where several people are bringing dishes. It travels well in a covered serving dish and is a welcome break from another heavy casserole.
