In my family we are always looking for something fast but healthy at the same time. I came across this recipe off the Betty Crocker site and it is so good!! Very easy to make and fast so you can put together and do other stuff why it bakes!!
Heat oven to 400. Grease bottom and sides of 13X9 pan, with non-stick spray or shortening. Sprinkle broccoli, and 2 cups cheese ,then the chicken and onion in baking dish.
Stir remaining ingredients until well blended. Pour over chicken mixture.
Bake uncovered 40 to 45 mins or until a knife inserted in center comes out clean. Sprinkle with the remaining 1 cup cheese. Bake 1 to 2 more minutes or until the cheese is melted. Let stand 5 minutes before cutting.
