Drain broccoli and place in 9x13 baking dish. Place chicken over top. In a bowl, combine all the soups, mayonnaise and lemon juice. Spread on top of chicken. Sprinkle with grated cheese. Mix dry bread cubes with melted butter and sprinkle on top of cheese. Bake at 350 for 35 minutes.
A viewer who tried this recipe, sent me her variation. It sounds interesting and may provide a bit of a different flavor. Instead of using 1 can cream of mushroom soup, 1 can cream of chicken soup and 1 can cream of celery soup, use only 2 cans cream of chicken soup. Also, I add 1/2 teaspoons curry powder, which adds a very interesting twist.
