This is the kind of dish that I like to serve at dinner parties simply because it can be prepared well in advance and then popped into the oven before your guests arrive.
Spicy sprouts, such as broccoli, arugula, or leek, give sushi rolls a delicate crunch and peppery flavor. A sushi mat makes it easy to wrap the nori and rice tightly around fillings, but it’s not necessary.
