Layer broccoli in a baking dish. Sprinkle a 1/4 cup of cheese over the broccoli. pound down the chicken breasts and spread them over the broccoli. Spread the rest of the cheese into the opened cans of cream of mushroom soup. Add the soy sauce and mix well. Spread over the chicken.
Place in a 350 degree oven and bake for 1 hour. I usually cover the sauce with Italian Bread Crumbs at about 45 minutes of baking time.
The Chicken comes out very moist. Serve with a salad and French Bread. I have served this a many dinners parties and was told it was delicious.
