Set the rice to cook according to packet instructions. Set aside once cooked.
Meanwhile trim any skin and brown flesh from the salmon and cut into a relatively small dice.
Mix together the soy sauce, rice wine vinegar, sesame oil and brown sugar. Toss the salmon in the soy mixture and set aside.
Peel and dice the avocado and mango.
Put together the 2 poke bowls by putting half of the rice in each bowl, then topping with half of the avocado, mango and edamame in little piles on one side.
Put half the salmon in each bowl on the other side, holding back most of the marinade as you take it out (a little in with the rice is good to add some flavor).
Sprinkle the sesame seeds over the top and serve.
Notes
You can easily use other fish, fruit, vegetables and toppings. Just make sure you use sushi grade fish, or eg cooked shrimp if you are less sure about raw fish.
