I have a family of 7, so you may want to cut the ingredients down. My 8 year old step-son is a very picky eater. If it doesn't come from a fast food place, we have to fight with him to eat dinner. Everytime I make this, he has at least 2 helpings of it.
Boil chicken and noodles until done. Boil broccoli until tender. Shred chicken into desired size pieces. Preheat oven to 350. Mix all ingredients, except for 2 handfuls of cheese. Put in casserole dish (for my family of 7, I use at least 3 dishes). Add remaining cheese on top. Bake in oven for about 15-20 minutes or until cheese is melted.
