Preheat oven to 350 degrees F. Spray a 13 by 9-inch baking dish with vegetable oil cooking spray.
In a large mixing bowl combine the chicken, celery, almonds, salt, pepper, lemon juice, mayonnaise, and cheese. Place the mixture in the prepared baking dish. Spread the crushed potato chips on top. Bake for 20 minutes, or until bubbly.
