Chicken Broccoli Casserole

Cooked broccoli, cauliflower, and carrots
Put in 9X13 pan.
Make white sauce on top:
Couple of tablespoons of butter, melt in pan. Add some flour. Then milk and a couple of tablespoons of cream cheese. Then more milk until you have enough of a white sauce to pour over the vegetables and chicken. The white sauce should be somewhat thick but not too thick.
Bake at 350 degrees for about 20 minutes.

Saltines
Melted butter
Parmesan cheese
