This is very easy to do! It not only looks cool, but it does serve a purpose! These spiral cut hot dogs cook without curling up...they're also great because the spirals help to capture all the condiments you put on top. And if you grill them, there is more surface area that gets all brown and flavorful! Or if you microwave them in a dish of water, like I did, they won't burst open!
