Great dish!!!

I have been making this dish for more than 20 years. I put the mixture in a pre-cooked deep dish pie crust and sprinkle the top with parmesan cheese. To cut down on calories I'm going to try it without the crust this year. I tell everyone it's a spinach quiche.

worth trying

I usually stay away from the frozen, boxed side dishes but we will be using this recipe again. Adding fresh mushrooms was an easy way to make it more "home made" looking. Though I don't recommend it, my husband ate it like it was the main course. Our one year old loved it.

Outstanding and Easy

This side dish makes you look like a gourmet chef. It is so easy to put together and it tastes so good! It now rivals the usual holiday side dishes! Even my mom loved it!
