For a low-carb alternative, try this cauliflower rice roll. Blend cauliflower florets in a food processor until they resemble rice grains. Steam the cauliflower rice until tender, then spread it onto a sheet of nori. Add thinly sliced avocado, cucumber, and carrot, and roll it up tightly. Slice into bite-sized pieces and serve with soy sauce for a healthy and satisfying option.
