I've been making this for 35 yrs, only differences are as follows: get the chopped frozen brococoli, cream of celery soup rather than mushroom, only a qtr cup of any milk, AND I add a can of sliced water chestnuts for texture. I use only half the chez whiz IN the casserole and drizzle the rest on top. The cheese needs to be melted first. As my 32 yr old daughter says when I take it out of the oven, "please mom, just pour it down my pants"! Trust me, this recipe is a keeper.
