Place the raw cauliflower chunks into your food processor with the blade attachment.
Blitz until it is a rice constancy
Place the riced cauliflower in a closed container and cook it in the microwave for three minutes
Once cooled, add the cream cheese, vinegar, salt and pepper. Blitz or stir until thoroughly mixed. You don't want any visible chunks of cream cheese or cauliflower, but you don't want a puree either
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, egg 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
