Absolutely! You can spiral cut the hot dogs and mix them with the sriracha honey sauce ahead of time. Place it all into an air-tight food storage container or leave it right in the mixing bowl, just make sure to cover the mixing bowl air-tight. Store it in the refrigerator for about 1 day, not longer. Then, grill them the next day. You can also make the coleslaw ahead of time and store it separately, in an air-tight food storage container, in the refrigerator.
