Preheat oven to 425°F. Grease a 13 x 9-inch baking dish or spray with nonstick cooking spray. In the prepared baking dish (or in a separate large bowl), stir together the Alfredo sauce, chicken broth, uncooked pasta, hot dogs, tomatoes, 1 cup of the cheddar cheese, chili powder, garlic powder, cumin, oregano, onion powder, and cayenne. Cover tightly with aluminum foil and bake for 35 minutes.
