I rarely make hot dogs, but when I do I usually make mac & cheese on the stove top as a side dish. During a recent lunch my son thought he would put the mac & cheese on the hot dog..."since it's all going to the same place anyway." The girls and I didn't know if we should be intrigued or grossed out. He said it wasn't bad, but he didn't repeat it on hot dog # 2.
PS. That's a line of ketchup across the top, in case you couldn't tell.
