Mini Mummy Hotdogs
This idea has been done so many times, I wouldn't know how to begin figuring out who to give credit for it.
It's very simple to do. Take crescent roll dough, cut the dough into thin strips, and wrap them around hot dogs to make them look like mummies (closer together around the body, and leaving an area for the face). Cook as directed on the package.
When they are cooked, add little dabs of ketchup (using a toothpick) and place sesame seeds (or poppy seeds) in the face area for eyes.
People often use whole hot dogs for this but I wanted to make cocktail-sized snacks for my party guests.
