Although caterpillars might be a delicacy in some countries, they're definitely not included in our Caterpillar Rolls. A Caterpillar Roll is a very popular and common roll. It's a safe "go-to" roll, especially since it doesn't have any raw fish in it. It's great for kids and for non-sushi lovers. Our version is very simple and consists of baked eel (unagi) in the center and topped with fresh slices of avocado on top, which is what lends to its name. Top it off with a sweet sauce and you have a basic roll that will surely please everyone.
