I made this dish for a pot-luck dinner at work. Jenny, from Thailand asked me what it was and I said, "chicken divan casserole". She thought I said "chicken in a van." We all got such a laugh out of it that it is now known as chicken in a van. Very easy and very good.
Spread broccoli in ungeased baking dish, 12x7x2 inches; drizzle with lemon juice. Top with turkey and cheese slices. Mix soup and milk; pour over chicken and cheese. Cook uncovered in 350 degree oven until hot and bubbly, about 30 minutes. Sprinkle with onion rings; cook 5 minutes longer.
Try different types of cheese. I've also substituted cream of broccoli soup for the cream of chicken. And you can never have too many French fried onions!
