Preheat oven to 450 degrees F.
Combine taco seasoning and salt; set aside.
On baking sheets make a single layer of French fries. Bake until golden brown, about 12 minutes and season with the spicy salt mixture. Serve with chili dogs.
Optional: When serving alongside chili dogs, scoop a spoonful of chili and a sprinkle of cheese on the fries for a delicious treat.
