Place the raw cauliflower chunks into your food processor with the blade attachment.
Blitz with the blade until small pieces of cauliflower rice appear.
Add the cream cheese, spring onion, vinegar, salt and pepper to the food processor. Blitz until thoroughly mixed. You don't want any visible chunks of cream cheese or cauliflower, but you don't want a puree either.
Taste the cauliflower rice and adjust the seasonings to your preference. Some like it with more salt or more vinegar than others.
Spread the cream cheese cauliflower rice mixture along the nori sheet, leaving 2 inches of the nori sheet bare.
Place your selection of vegetables, avocado and fish along the centre. Dampen the bare edge of the nori sheet then roll up tightly.
Repeat with the remaining nori sheets and fillings. Slice with a sharp wet knife.
Serve with wasabi, soy sauce or coconut aminos.
