Cut the mango, avocado, and raw fresh salmon into thin slices.
Use 2 nori sheets per wrap. Place them on top of each other and gently fold them twice (both ways) to get four square marks. Cut a slit on one line up to the center of the nori sheets, using scissors.
Place half of the ingredients on each square, starting from the bottom left corner and going clockwise in the following order: avocado, mango, salmon, and rice.
Add sriracha and mayo on the salmon, and furikake or sesame seeds on the rice.
Carefully lift the bottom left corner with avocado and fold it on top of the mango. Press gently for them to stick together.
Fold the top left corner to the top right corner with salmon. Then fold again over the rice to make one square-shaped nori wrap.
Repeat with the other 2 nori sheets and the other half of the ingredients.
Enjoy immediately for the best texture and taste. Bon appetite!
