Don't you just love those "make ahead" casseroles? It just seems so much easier sometimes to throw together a few ingredients, pop it in the fridge overnight, then voila! Dinner is ready to throw in the oven when the family's ready to eat.
You'll also like the fact that you can use up some leftovers with this simple casserole. Use any vegetables you happen to have in the fridge. This is also a great recipe to plan when you make a big pot roast with the intentions of having extra meat for another meal.
