A couple years ago, I lived next to a girl from Hawaii. She was totally broke all the time and missed sushi something fierce, so we decided to make it together. It was cheaper than ordering out and since she knew how, it really wasn't difficult. The best part was finding out that, where she's from, it's apparently totally acceptable to wrap sushi rolls and not cut them, eating them like a burrito instead of piece by piece. This cuts down on a LOT of work.
But even making rolls is too much work sometimes. That's when I make bowls. In fancy chef-speak, this would be called a "deconstructed California Roll". In real world-speak, I dumped all the ingredients in a bowl and hoovered it up as only an American can.
