I saw these from Boing Boing a while back and thought they were cool and my kids would love them. So the other night, when I was at a little lost at what to make for dinner. I found a pack of hot dogs leftover from a recent BBQ and decided to try it out.
It's actually trickier than I thought to thread raw spaghetti through hot dogs. The noodles are pretty brittle. I found that doing a few spaghetti at a time helped a little, but mostly the key is to not worry too much about threading them through perfectly. They'll look fine once cooked.
The other important thing is to cook the noodles for a minute or two longer so the part that is inside the hot dog is cooked all the way too. It's not a big deal. Mixed in with the hot dog, my kids probably didn't even noticed if the spaghetti wasn't cooked all the way.
I ended up cutting between the hot dog segments to make them look more wild. They were a fun meal for the kids. I even brought a few to work the next day as a snack. Fun for all ages!
