Cook the sushi rice according to the package directions. Combine vinegar, sugar, and salt, and heat until the sugar and salt dissolve. Add the mixture to the cooked rice and stir to combine.
Slice the avocado and cucumber. Cut the nori sheets in quarters.
Dice the salmon filet into 1 cm cubes. Mix it with Sriracha, mayo, garlic and lemon juice. Set aside.
Soak the rice paper in water for a few seconds, till it's soft.
Place a piece of sushi seaweed in the middle of a sheet of rice paper.
Spread a thin layer of sushi rice over the nori. Arrange salmon, avocado, and cucumber over the rice. Cover the filling with the other piece of sushi seaweed.
To roll the sushi, fold the bottom edge of the rice paper up over the filling, then fold the sides in towards the center. Roll the sushi tightly from the bottom up until it forms a cylinder shape. Coat the roll with some sesame seeds.Repeat with the remaining ingredients. Place some olive oil in a large skillet over medium heat until hot but not smoking. Fry the rolls till golden brown and crispy on all sides, about 1 minute for each side.
Remove the rolls from the skillet and place them on a paper towel-lined plate to drain off any excess oil. Serve the rolls with soy sauce, wasabi, and pickled ginger on the side. Enjoy!
