This is my version of Cindy's Chicken Broccoli Casserole.
2   10 oz pkg frozen broccoli - cooked and drained
1 chicken cooked and cut up  ( I now buy the rotisserie chicken cooked  and de-bone it)
Melt together -
2 cups cheese
2 can cream of mushroom soup
1/2 cup milk
2 shakes  Worcestershire sauce
1 TBSP  lemon juice
1/4 tsp pepper
1/2  tsp salt
1 small onion, grated
Topping -
2 additional cups grated cheddar cheese  - for topping (optional)
1 can onion rings
To assemble -
Put cooked  broccoli on bottom of casserole dish.
Top with 1/2 of the cheese sauce
top with cut up cooked chicken
add the rest of the cheese sauce
If desired, top with additional grated cheese and  a can of onion rings
Crunch up 1 can onion rings and top casserole with this.
Bake at 350 for 40 - 50 minutes.
