Rinse the sushi rice under cold water in a fine-mesh sieve until the water runs clear to remove excess starch. In a medium-sized pot, combine the rinsed rice with 2 1/2 cups of water. Bring the mixture to a boil over medium-high heat. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 20 minutes. After 20 minutes, remove from heat without lifting the lid and let it sit for an additional 10 minutes to finish steaming.
In a mixing bowl, combine the mayonnaise and sriracha, stirring well until smooth and fully blended. Set the spicy mayo aside for later use.
While the rice is resting, prepare the salmon. Season the salmon fillet with soy sauce on both sides. Place the seasoned salmon onto a baking sheet lined with parchment paper. Bake in the preheated oven for approximately 12-15 minutes, or until the salmon is fully cooked and flakes easily with a fork. Once done, remove it from the oven and allow it to cool for a few minutes.
After the salmon has cooled, flake it into small pieces using a fork or your hands. In a bowl, combine the flaked salmon with half of the spicy mayo, mixing gently until well coated.
In a large baking dish, evenly spread the cooked sushi rice across the bottom. Using a spatula, gently press the rice down to create an even layer.
Evenly distribute the salmon mixture over the layer of rice, making sure to cover it completely. Then, drizzle the remaining spicy mayo over the top of the salmon layer.
Return the baking dish to the oven and bake for an additional 10-15 minutes, or until the top is slightly crispy and has turned a lovely golden color.
Once baked, remove the dish from the oven and let it cool for a few minutes before slicing into squares for serving.
Top each square with slices of avocado, a sprinkle of chopped green onions, and a few sesame seeds for added flavor and texture. Garnish with nori strips for a beautiful presentation.
Serve warm, accompanied by pickled ginger and additional sriracha on the side for those who enjoy an extra kick.
