Cook the rice by placing it in a bowl and rinsing it under cold water at least 3 times. Place the rice and 350ml of cold water in a saucepan and bring to a boil. Reduce the heat and allow to simmer until all the water’s been absorbed. Divide the rice between two bowls and allow to cool.
Prepare the sauce for the tuna by mixing together the soy sauce, lime juice, rice wine vinegar, sesame oil, sesame seeds, chilli flakes and the crushed nori.
Cut the tuna into small cubes and mix with half the sauce. Allow to marinate for 10minutes then place the tuna on top of the rice.
Slice the avocado and radishes and add to each bowl. Serve the Poke bowl with the remaining sauce.
