I took this to a Thanksgiving potluck. It was very popular, and I liked it even though I'm not usually a broccoli fan. I substituted cubed Velveeta cheese for the Cheez Whiz (cooking with that stuff seemed sort of gross to me), and I used cream of chicken soup instead of cream of mushroom. I also doubled everything and used a 9x13 casserole dish. Very successful -- everyone wants me to make it again!
