Prep
In Joyce's words: "Sauté onions and cut up mushrooms in oil. Cook barley. Mix barley and mushrooms with one package of onion soup mix. Mix it together like a pilaf." Beef broth gives it depth; vegetable broth is the only thing standing between this and vegetarian. Reheats better than most grain dishes - warm it in a pan with a splash of broth, not the microwave.
