Rinse the sushi rice under cold water until the water runs clear. Combine the rinsed rice and water in a saucepan and bring to a boil. Once boiling, reduce the heat to low, cover and let it simmer for about 18 minutes, or until the water is absorbed and the rice is tender.
Once cooked, remove the rice from heat and let it sit covered for an additional 10 minutes. In a small bowl, mix together the rice vinegar, sugar, and salt until dissolved. Fluff the rice with a fork and fold the vinegar mixture into the rice gently. Set it aside to cool.
In a separate bowl, mix the chopped salmon with sriracha sauce and mayonnaise until well combined.
In a baking dish, spread an even layer of the sushi rice across the bottom.
Spread the spicy salmon mixture over the rice evenly.
Place the dish in the oven and bake for about 15-20 minutes or until the salmon is cooked through.
Remove from the oven and let it cool for a few minutes.
Top the baked sushi with sliced avocado, cucumber, chopped green onions, and a sprinkle of sesame seeds.
Serve warm, garnished with nori squares on the side for wrapping or crumbling on top.
