In a large bowl, combine the chicken, celery, 1 cup of the bread cubes, the mayonnaise, 1/2 cup of the cheese, the almonds, lemon juice, minced onion and salt. Spoon mixture into prepared baking dish. Top with the remaining bread cubes and cheese.
Bake at 400 degrees F for 20 minutes, until bubbly. Serve warm or at room temperature.
