  • 2 teaspoons kosher salt
  • ½ teaspoon ground mustard
  • ¼ teaspoon garlic powder

  • Preheat the oven to 350°F and spray a 9x13-inch baking dish with nonstick cooking spray.
  • In a medium saucepan over medium heat, melt the butter.

  • In a large bowl, add cooked noodles, cheese sauce, chicken, diced tomatoes, salt, and pepper. Toss to coat.
  • Pour into the prepared baking dish and top with the remaining 1 cup of cheddar cheese.
  • Bake uncovered for 25-30 minutes, or until cheese is hot and bubbly.
  • Garnish with parsley (optional) and serve hot.
