Place a well-seasoned cast iron skillet over medium-low heat. Once hot, cook the hot dogs for a few minutes until seared. Then remove and spray skillet lightly with non-stick spray.
Add cheddar cheese to skillet in about 1/3 cup portions. Try to shape into an oblong shape to match the hot dogs. Let the cheese melt and bubble. When cheese stops bubbling and starts to get crispy around the edges, place a seared hot dog on one side of the cheese and use a spatula to rolll up the hot dog.
If the cheese sticks to the skillet at all, use a good spatula or a butter knife to loosen the cheese around the edges and it should eventually release.
If you aren't eating immediately, you can keep hot dogs warm in a 250˚F oven.
Serve cheese blanket hot dogs in buns with mustard, diced onion and peppers, and any other toppings you like.
