Using a food processor, rice the cauliflower into rice-sized pieces by pulsing.

Slice the cucumber on each end, then place the cucumber upright and slice off each side.Discard the middle and slice about 2 side pieces into small strips. Set aside in the fridge.

In a very hot pan, add cauliflower rice and cook. Season with soy sauce as the cooking process happens, about 1 tbsp.

Once the cauliflower is finished up and dried out some, add to a bowl with cream cheese and rice vinegar. Mix together well and set in the fridge until cool.

Once the rice mixture is cooled, slice 1/2 an avocado into small strips and scoop out of the shell.

Put a nori sheet down on a bamboo roller covered with saran wrap (this helps with sticking). Spread some of the cauliflower rice mixture over the nori sheet, add fillings and roll tightly.
