I've been making this dinner look-alike for years, but it still makes me smile every time. It's also surprisingly simple--just make some crispy rice treats, and either top them with some Swedish fish, or roll them around gummy worms and wrap them in Fruit Roll-Ups. Honestly, the hardest part is finding green Fruit Roll-Ups--it seems all of the stores around me only carry berry flavors or crazy swirled varieties. This is a great recipe to make with kids, and it's a fun way to end a (legitimate) sushi dinner.
