Preparation
Start the water boiling for the macaroni. (Hint: 1 2/3 cups uncooked macaroni typically cooks to about 2 1/2 cups.) Preheat the oven to 350 degrees. Spray an 8-by-8-inch baking dish with butter-flavored cooking spray.
In a large skillet, combine mushroom soup, skim milk, onion flakes, parsley flakes, and black pepper over medium heat. Add the Cheddar cheese, stirring often, until cheese melts.
In the meantime, cook the macaroni according to package directions. When done, drain well.
Add macaroni, peas and ham to the soup mixture. Mix well to combine.
Spread mixture into prepared baking dish. Bake 30 minutes. Place baking dish on a wire rack and let set 5 minutes. Cut into 6 servings.
