If you're strapped on ingredients, there are plenty of things you can put in sushi rolls — aside from avocado, fish, and veggies, you can try mixing it up with fruit, nuts, or whatever meats you have on hand. It's important to note these inclusions are by no means how sushi is traditionally made, but quarantine sushi is a whole new ballgame, y'all.
Promising review: "When people started talking about how even their child could make sushi rolls with this, I knew that I had to try it. I'm a decent cook, but when it comes to operating even the simplest of apparatuses, I'm not the most talented person. But, lo and behold, when I used this kit, making the rolls was easy and as quick as this task will ever get. I just stuff some pre-cut carrot matchsticks, some thin avocado slices, some thin (seeded) cucumber slices, and roll the nori and rice into a lovely roll. This one goes out to all those adults that never try anything new because why bother: You can do this!!!" —Mr. Martha Stewart
