Great starter recipie

Great recipe from which to make your own additions.  I've experimented by adding some of the following depending on the tastes of my guests.  Ground turkey, mushrooms, Italian sausage, even parsnips for a different flavor, Certainly not all at the same time. This is also an easy dish to make that allows the use of half the side of your baking dish if you know someone won't eat one of the above ingredients. Even my wife likes this and she's a fussy eater.

this was awesome! followed exactly, but microwaved veggies separately & forgot to chill in ice water. a step i will not add next time. might add broccoli, tho. 4T of horseradish seemed like alot, but was very good & not too much at all. used crushed cheddar/garlic croutons on top. everyone loved this!!! served with roasted vegetable sandwiches. could use as a holiday dish.
