Forget casseroles! Condensed cream of mushroom soup gets an elegant makeover in this easy-to-assemble pie. If you’re looking to get ahead and save money, buy sliced and boxed mushrooms when they go on sale; then make the filling, freeze it, and whip up the quiche when you’re ready.
For an hors d’oeuvre version of this dish, stuff button mushrooms with a spoonful of the millet filling, and bake 10 minutes. In addition to saucepan cooking directions, we’re including instructions for cooking millet in a rice cooker, which yields soft, fluffy results.
