Rice and sushi without rice

Ingredients:

1 big or about 400 gr. of cauliflower
salt, spices, herbs, sauce, etc.

For sushi: 

Nori seaweed
about 30 gr of avocado or cashew cream

Instructions:

Steam cauliflower for about 8 minutes, it must be “al dente”. If you eat raw, then don’t cook it.
Grind up cauliflower in a food processor until you get the texture of a rice. Add salt, spices, etc. Keep aside or serve with tomato sauce, oil, or any sauce you want, vegetables or any other ingredient.

For Sushi:

If you prefer avocado, then blend it until you get a cream. If you prefer cashews, then dilute it in water until you get a cream that is easily spread and mixed with the cauliflower.
Mix the avocado or cashew cream with cauliflower. The cauliflower rice must keep a little bit sticky, like sushi rice. Add more cream if it's not sticky enough.
Add all ingredients you want for sushi: vegetables, fish, mango, etc.
Spread mix on the seaweed. Proceed as usual to make sushi.
