In a small bowl add tune, mayo, sweet chilli sauce and sriracha. Mix well.
In another bowl add rice and the optional rice seasoning. This will add extra flavour and the taste you’ll recognise from sushi. I put it as optional as not everyone might have all the ingredients, and if you dont have it, plain rice will do, you’ll still have a tasty recipe!
Now add a layer of rice to the nori sheet, the. The tuna mix and avocado.
Close the nori sheet by bringing the opposite corner together. To help you keep everything thigh inside you can use a bit of cellophane. Cut in a half and enjoy!
Notes
Optional for the rice:1 tsp each of: soy sauce, white rice vinegar, sesame oil
